Design and Function 7.0
1
Intended Use 7.1
The Multi Switch is intended to control up to four devices/technical aids with one input device (mechanical
or proximity switch). The mechanical switch is only intended to support auxiliary wheelchair function. The
Multi Switch oers the user greater freedom of operation and increased function control. The switch is USB
powered and contains its own control electronics.
The Multi Switch is also available as part of a package which includes proximity sensors. The sensors can be
used as input devices and require no force to activate. The addition of mo-Vis proximity sensors increases the
level of autonomy aorded the chair user.
Multi Switch Features 7.2
mo-Vis' Multi Switch features:
• one 3.5mm stereo input jack, allowing a mechanical switch or proximity sensor input connection;
• two 3.5mm stereo output jacks, allowing up to four separate outputs (with splitter cables, sold
separately);
• a LED for each output channel, indicating status and activity of the channel;
• clear, audible feedback;
• fully adjustable input and output parameters via conguration software; and,
• multiple mode settings.
Proximity Sensor Features 7.3
mo-Vis proximity sensors, sold separately from and compatible only with the Multi Switch, feature:
• two size options:
• 12mm for installations with limited space; and,
• 24mm for installations requiring increased sensitivity.
• sensitivity adjustment via congurator software; and,
• easy calibration and conguration.
CAUTION
Moisture (e.g., rain) is a conductive substance. While a negligible
amount of liquid may not interfere with device operation, a coating
of moisture can cause the sensors to constantly read as activated.

Mounting the Multi Switch 8.2
Its exceedingly small size grants the Multi Switch nearly unlimited mounting options.
The use of hook-and-loop adhesive patches is recommended when mounting the switch.
(Note: Hook-and-loop adhesive patches are not included with the Multi-Switch.)
CAUTION Keep devices that emit radio frequencies (e.g., mobile phones)
at least 30cm (12") from the sensor and its connecting cable.
NOTICE Only install this product on wheelchairs onto which
the manufacturer allows the installation of third-party parts.
CAUTION
In case high sensitivities are utilized for sensors (70%),
ensure the sensor is rmly xed and its cables routed in a way
that avoids kinks or obstructions. Moving the sensor or its cables
can inuence its sensitivity, possibly producing false activations.
NOTICE
Ensure the user has unobstructed visual contact with the LEDs
on the front of the Multi Switch, in order to check its status.
Although every activation is able to trigger an auditory signal, it is not
recommended to rely on this alone for activation conrmation.
CAUTION
The Multi Switch is not waterproof. While a few drops of water
will not likely cause problems, the device should be mounted
in such a way as to ensure that water cannot enter the device.
NOTICE
The electronics of the Multi Switch can be aected by external electromagnetic
elds (e.g., elds generated by mobile telephones). The electronics themselves can
also emit electromagnetic elds that can aect electronics in their immediate
surroundings (e.g., certain electronic alarm systems). The limit values for
Electromagnetic Compatibility (EMC) with respect to this type of device are set in
the harmonized standards for the EU in the Medical Device Directive, No. 93/42/
EEC. The Multi Switch unit and its proximity sensors comply with these values.

USB Power Supply 9.1
The Multi Switch is powered by means of a micro USB connection. When the device is plugged into a USB
power source, such as a USB charger, a laptop, or a power bank, the device will be powered and ready to use.
The Switch requires a minimal amount of energy. Some power sources are not designed to deliver minimal
current over long durations. Accordingly, proper device functionality is not guaranteed with any power
source.
Contact your dealer or mo-Vis for more information and for assistance with choosing the correct power source
for the Multi Switch.
Output 9.3
Input 9.2
The Multi Switch has a single 3.5mm
input jack, which is compatible with two
types of switches:
The Multi Switch is equipped with four green LEDs
on the device's face that indicate its output. They
indicate the channel currently selected, and shifts to
select the desired channel.
A separate green LED on the face of the device
indicates the device status.
When used with a splitter cable (sold separately), the
Multi Switch is capable of four output functions.
Switch Type: Input:
Mechanical Use a switch equipped
with a 3.5mm mono jack
Proximity Use mo-Vis
proximity sensors
Status: LED Action:
Active - Short blink, long pause
Fault - Series of blinks, long pause
(error, see troubleshooting)
Outputs: Location:
1,2 Green mono jack
3,4 Yellow mono jack
CAUTION
A ground loop can be introduced into the connection if the USB port and the input jack
are plugged into circuits powered by the same battery. This can cause a grounded current to
ow from one circuit to another through the Multi Switch, and if the current is too high,
the Multi Switch can be over-stressed and may not function properly, leading to permanent
damage to the device. One way to avoid introducing a ground loop to the connection is to
connect the device to an isolated USB power supply.

Proximity Sensor Information
The mo-Vis proximity sensor is based on the
principle of capacitive sensing. It is capable of
measuring objects (e.g., a nger or metal stick)
that approach the sensor. The larger the surface
of the sensor, the more sensitive it will be (the
24mm being the most sensitive). The sensor is
most sensitive at its front in the center. Its sides
are slightly sensitive, and the underside is immune.
mo-Vis provides a congurator software on its website (www.mo-vis.com) or Stealth Products website
(https://www.stealthproducts.com/p/52/) that enables users to adjust and customize nearly every aspect of
the Multi Switch's operation. For details on how to install and use the software, the user is advised to consult
the congurator software manual, included in the software download.
- Windows 7, 8, or 10 is required to run the software.
With Dealer-level software access, you will be able to congure a number of parameters for the Multi Switch.
- Dealer-level access requires a password.
To obtain a password for the software, call Stealth Products at [phone] or toll-free at [phone]
and speak to a customer service representative.

Click Mode:
To generate one or more short clicks, quickly open and close (activate and deactivate) the
input. (The period between the clicks has to be shorter than the 'Action Delay' time.)
After the clicks are input,
- The output will be closed for a set time (depending on the output's 'Close Time' setting), or
- the selected output will remain locked until released (depending on the output's 'Lock' setting).
Start Scan:
A quick click (input activation) will begin a scan of available active outputs.
- A number of beeps corresponding to the number of available active outputs will be generated, and
- a corresponding selection LED will be activated.
When the desired output is indicated, click (activate) the input again to select and activate
the output. The output will react.
- The output will remain closed as long as the input is closed, or
- the output will remain locked until it is manually deselected (depending on the output's 'Lock'
setting).
The scanning of the outputs is done at an interval of 'Select/Scan Time'.
(Note: If too much time elapses without selecting and activating an output, the selection process will stop and no
output will be activated. This is a built-in feature designed to allow any unwanted input to be canceled.
Mode Select
Hold and Scan:
Activating and holding the input will begin a scan of available active outputs.
- A number of beeps corresponding to the selected output will be generated, and
- a corresponding selection LED will be activated.
When the desired output is indicated, release the input to select and activate the output.
The output will react.

Technical Data 9.0

Select Timed Click:
Selection in this mode is dependent on duration and number of clicks.
- For outputs 1 to 3, keep the input closed to scan the outputs. A number of beeps and
corresponding LED will be activated.
- Output 1: Short press (<Select/Scan Time)
- Output 2: Medium Press (>Select/Scan Time)
- Output 3: Long Press (>2x Select/Scan Time)
- For output 4, double click (within the Select/Scan Time)
When the desired output is indicated, release the input again to select and activate the
output.
-The output will remain closed for a set time (depending on the output's 'Close Time' settings), or
-the output will remain locked until it is manually deselected (depending on the output's 'Lock'
setting).
(Note: If too much time elapsed without selecting and activating an output, the selection process will stop and no
output will be activated. This is a built-in feature designed to allow any unwanted input to be canceled.
Continuous Scan:
In this mode the active outputs are scanned continuously.
When the desired output is indicated, close the input to select and activate the output.
- The output will remain closed as long as the input is closed, or
- The output is locked until released (depending on the output's 'Lock' setting)
- The output will remain closed as long as the input is closed, or
- the output will remain locked until it is manually deselected (depending on the output's 'Lock'
setting).
(Note: If too much time elapses without selecting and activating an output, the selection process will stop and no
output will be activated. This is a built-in feature designed to allow any unwanted input to be canceled.)

'Lock Mode' is designed to allow the user to control and activate a device for longer periods of time (e.g.,
with a communication or environmental device).
When 'Lock Mode' is set to active, it will be locked in the selected output. To unlock this mode, the input
needs to be closed (activated) and held shorter/longer than the 'Quit Time', depending on the setting.
Lock Mode options are:
No (default): normal operation, after the input was operated, return to selection mode.
Timed Closed: the output will be locked in the selected output mode. To escape this mode (i.e. to break the
lock), close the input continuously for longer than the 'Quit Time'. When working in this mode, the output
will be closed when the input is closed. This means that when you break the lock, your output will react as
well.
Timed Open: The output will be locked in the selected output mode. To break the lock, close the input
continuously for a time longer than the 'Quit Time'. When working in this mode, the output will be closed
when the input is released.
Nudge: The output will be locked in the selected output mode. To break the lock, close the input for a time
shorter than the 'Quit TIme'. The output will be closed only if you hold longer than the 'Quit Time'.
Lock Mode
Momentary/Timed:
- The output will remain closed as long as the input is closed, or
- the output will be closed for a set time.
Switched:
- the output will toggle between open and closed. This is useful to switch something on continuously.

Auto:
The system will make automatic adjustments over time. (Note: This is only a usable setting for situations in
which the user of the device is able to maintain a distance of at least 30mm (12") from the sensor when
he/she is not operating it.)
Manual:
Have the user determine at what point he/she would like the input to be considered open/activated. When
that position is reached, press the push button on the front of the switch box, and the system will store that
position as the open reference.
When the calibration is successful, a continuous beep will sound. If the calibration has been unsuccessful
(i.e., if 'Calibration Mode' is set to Auto or a mechanical switch is connected), a series of short beeps will
sound.
Manual calibration mode is necessary when the activating part of the user's body remains constantly closer
than 30mm (12") to the sensor. If this is the case, manual calibration should be undergone regularly.
Calibration Mode
WARNING 'Calibration Mode' can only be used to calibrate proximity sensors.

Flash Codes:
When a fault occurs, the output LED will begin to ash. There will be a long delay followed by a
number of ashes with a short delay. Count the number of ashes, then nd the corresponding
information in the table below.
Error Codes:
The Multi Switch maintains a fault log with fault counters. Each time a specic fault occurs, its
counter will be incremented by one. The fault log can be accessed by the congurator (Dealer-level
prole access). This user can clear one or all of the errors from the fault log.
In the case of error codes, please contact mo-Vis to learn about the required actions.
Should a problem persist after corrective action, please contact your local dealer or mo-Vis service
