BlueSwitch User Manual
Thank you for purchasing BlueSwitch! BlueSwitch is a Bluetooth hub
for interfacing to switch accessible devices. BlueSwitch enables the
switch user to connect as many as three external switches to control
up to three Bluetooth devices (cell phones, computers, tablets). The
user has the ability to cycle through the Bluetooth devices and select
the device they want to control. In this way, one set of switches
controls up to three different devices. In addition, the user can choose
to output their switch activations to two relays, enabling the user to
control wired devices such as a nurse call button.
Left Side of BlueSwitch 2
Input Switches
There are three switch jacks and buttons labeled SW1, SW2, and SW3.
This is where you will connect the user’s switches. BlueSwitch accepts
any 3.5mm mono switch output, such as a push-button switch or the
output of a Sip-and-Puff switch. The small
buttons beside each switch jack are there for
convenience to test the functionality of
switches during setup –pressing a button is
identical to activating its associated switch.
All three switch inputs DO NOT provide the
same functionality. It is important to connect
the switches to the correct switch input as
described in the “Switch Configurations”
section, based on the user’s desired
configuration.
Relay Outputs
There are two jacks labeled “Out 1” and “Out
2”. These are relay outputs, allowing the user
to connect wired devices they wish to control
such as a nurse call button. The relays support
a maximum of 1 amp of current and 30 volts
DC. Exceeding these specifications will damage
BlueSwitch.

Right Side of BlueSwitch 3
Charging Port
The Micro-B USB jack labeled “CHG” is used to charge the device.
When the provided USB cable is connected and powered, the device
will charge. On the front of BlueSwitch is a battery symbol with four
LEDs that display the current battery status. When the device is
charging, a battery LED will blink.
Unpair Button
This button is used to disconnect BlueSwitch from
all Bluetooth devices. This includes forgetting all
the devices which BlueSwitch attempts to
reconnect to on power up. To do so, hold down
the Unpair button for three seconds until a long
beep is heard.
On/Off Switch
The switch labeled “ON” is the on/off switch. To
turn the device on, slide the switch upward
towards the DIP switches. To turn the device off,
slide the switch downward towards the charging
jack. A green LED above the switch also indicates
when the device is turned on.
DIP Switches
The light-blue DIP switches enable switching
among basic configurations without using the
BlueSwitch Android app. These configurations are
discussed in detail in the section “DIP Switch
Settings”.
Front of BlueSwitch 4
Active Sw. LED
The Active Sw. LED glows green when SW1 is activated, red when SW2
is activated, and orange when SW3 is activated. The Active Sw. LED will
blink orange when attempting to auto-reconnect to previously
connected Bluetooth devices.
Device 1/2/3 LEDs
These LEDs indicate when
Bluetooth devices are
connected to BlueSwitch. Each
LED will glow green when that
device is connected. The
device’s LED glows orange when
it is selected as an output device
for switch activations. If all the
device’s LEDs are green or no
Bluetooth devices are
connected, switch activations
are sent to the relay outputs
instead of to a Bluetooth device.
Battery Symbol
The battery symbol has four LEDs that display the battery power
status. When the device is charging, a battery LED will blink.

Pairing BlueSwitch to a Bluetooth Device 5
1) Turn on BlueSwitch.
2) On your phone/tablet/computer, navigate to the device’s
Bluetooth settings. Ensure your device’s Bluetooth is turned on.
3) In your device’s settings, scan for available Bluetooth devices.
Look for a device named “BlueSwitch” and select it.
If “BlueSwitch” fails to show up as an available device,
turn your device’s Bluetooth off then back on then re-
scan for available devices.
If that doesn’t work, turn BlueSwitch off then back on
and re-scan for available Bluetooth devices on your
device.
4) Once the connection is successful, the next Device LED on the
front of BlueSwitch will glow orange indicating it has a
Bluetooth connection and the device is currently selected as
the output device.
DIP Switch Settings 6
The four DIP switches on the right side of BlueSwitch provide basic
configurations without the need to use the free BlueSwitch Android
app. This section describes the functionality of BlueSwitch depending
on the status of each individual DIP switch. Each DIP switch is
numbered above it, starting with ‘1’closest to the On/Off switch. The
DIP switches are considered ‘off’ when slid downward towards the
back of BlueSwitch and ‘on’ when slid upward towards the front of
BlueSwitch.
DIP Switch 1: When 'off', BlueSwitch is in standard mode, which
enables the options controlled by the next three DIP switches. When
'on' BlueSwitch is in custom mode, which disables the functionality of
DIP switches 2, 3, and 4 and instead uses the switch settings from our
free BlueSwitch Android app available on Google Play.
DIP Switch 2: When 'off', BlueSwitch sends the numbers '1' and '3' via
Bluetooth. When 'on', BlueSwitch sends 'space' and 'enter' via
Bluetooth. These are common characters used for Bluetooth switch
access.
DIP Switch 3: When 'off', a switch activation is sent via Bluetooth when
the user’s SW1 is pressed. When ‘on’, a switch activation is sent when
the user’s SW1 is released.
DIP Switch 4: When 'off', a switch activation is sent via Bluetooth when
user’s SW2 is pressed. When 'on', a switch activation is sent when
user’s SW2 is released.

Switch Configurations 7
This section describes how to setup the DIP switches for common
BlueSwitch users. If you need additional customization, you can
download our free BlueSwitch Android app found on Google Play.
Please contact us if you need assistance configuring BlueSwitch.
Three Switch User
If the user can activate three switches, connect each switch to inputs
SW1, SW2, and SW3. This will allow the user to output two Bluetooth
switch activations with SW1 and SW2 and cycle through connected
Bluetooth devices with SW3. A common use for this configuration
would be 2-switch step scanning or 2-switch operating system control,
with an additional dedicated switch for cycling through connected
devices.
For this mode, ensure DIP Switch 1 is ‘off’. The functionality of SW1
and SW2 is dependent upon DIP Switches 2 - 4, as described in the “DIP
Switch Settings” above.
Two Switch User: Both Switches Used for Switch Activation Outputs
This configuration outputs a Bluetooth switch activation on each
switch (SW1 and SW2) and also cycles through connected devices by a
long press on SW1. The two switches should be connected to SW1 and
SW2. A common use for this would be for 2-switch step scanning or 2-
switch operating system control, while cycling through connected
devices by a long SW1 switch press.
For this mode, ensure DIP Switch 1 is ‘on’. A short press (less than 1.5
seconds and before BlueSwitch beeps) on SW1 will output a Bluetooth
switch activation on release and SW2 will output a Bluetooth switch
activation on press. To cycle between connected devices, perform a
long press on SW1 by holding down the switch for 3 seconds until the
Active Sw. LED turns orange and there is a double beep sound.
Switch Configurations 8
Two Switch User: One Switch for a Single Switch Activation Output,
One Switch for Cycling Between Devices
This configuration enables one switch for a single Bluetooth output and
one switch dedicated to cycling among devices. The switch used for
Bluetooth output should be connected to SW1 and the switch used to
cycle between connected devices should be connected to SW3.
For this mode, ensure DIP Switch 1 is ‘off’. SW1 functionality is
dependent upon DIP Switch 2 and 3, as detailed in the “DIP Switch
Settings” above.
Single Switch User
If the user operates a single switch, their switch should be connected
to SW1. With this configuration SW1 can be used to output a single
switch activation to connected Bluetooth devices, output two different
switch activations to connected Bluetooth devices differentiated by a
short or long press, or cycle among connected devices using an
extended long press.
For this mode, ensure DIP Switch 1 is ‘on’. Switch activations are output
upon release of the switch. The first Bluetooth output occurs with a
short press on the switch (less than 1.5 seconds and before BlueSwitch
beeps). To perform the second Bluetooth output, perform a long press
on the switch until the Active Sw. LED is red (greater than 1.5 seconds
but less than 3 seconds or said another way, after BlueSwitch beeps
once but before it beeps twice). To cycle between connected devices,
perform an extended long press on the switch until the LED turns
orange (holding down the switch for 3 seconds or until it double
beeps).

BlueSwitch Android App 9
While many user configurations can be addressed with the DIP Switch
settings previously described, we understand the need for complete
customization and control. BlueSwitch has a companion Android app
on Google Play. This app is only available for Android.
To use, download the
BlueSwitch app to your Android
device. Connect your device via
Bluetooth to the BlueSwitch
hardware following the steps
detailed in “Pairing BlueSwitch
to a Bluetooth Device” section.
Once connected, you can open
the app and change BlueSwitch
settings.
Once you’ve changed settings in the app, you must send your settings
to BlueSwitch for them to take effect. To send your changed settings,
click the “Send Values” button which is found in the top right corner of
the app. Figure 5
highlights this location
with a red circle.
Settings are persistent
and will be saved to
BlueSwitch even after
BlueSwitch has been
powered on and off.
BlueSwitch Android App 10
Below is a list of settings which are customizable through the
BlueSwitch Android app:
Enable short and long switch presses for SW1 and SW2.
Set the long switch press duration for SW1 and SW2.
Choose to output switch activations on switch press or switch
release for SW1, SW2, and SW3.
Set an acceptance time before sending out a switch activation
for SW1, SW2, and SW3. If the acceptance time is not met,
nothing is sent. This is helpful for people who tend to
accidentally reactivate their switch when pressing or releasing.
Set the extended long press duration to cycle through
connected Bluetooth devices on SW1.
Set which HID character to send on switch activation for SW1
and SW2. Options include characters A-Z, F1-F12, 0-9, Space,
and Enter.
Enable the feedback beeper which indicates when a long press
duration has been reached.

Using Relay Outputs to Control Wired Devices 11
The relay outputs labeled “Out 1” and “Out 2” located on the left side
of BlueSwitch enable the user to connect and control wired devices
such as a nurse call button. The relays support a maximum of 1 amp of
current and 30 volts DC. Exceeding these specifications will damage
BlueSwitch.
To control the relays, cycle through connected Bluetooth devices until
the Device LEDs on the front of BlueSwitch are all green. Switch
activations will then be sent to the relay outputs. If no Bluetooth
devices are connected to BlueSwitch, switch activations are
automatically sent to the relays. SW1 activations are set to “Out 1”
and SW2 activations are sent to “Out 2”.
