Introduction
Thank you for purchasing the EZ-ON This product will make your life easier by allowing you to
control any household wall switch wirelessly. Perfect for the bedroom; where you can now turn
off the light without getting out of bed. Also great for outdoor porch lights, garbage disposals,
ceiling fans, anything you would normally control via a wall switch. You can feel confident about
your purchase with our satisfaction guarantee or your money back Please see also your new
products lifetime warranty packet.
Features
•Easy to use and convenient for anyone.
•Control any hardwired wall switch.
•Remote controller with sufficient range for any room.
•Indicator LEDs for ON and OFF.
•Pushbutton at Receiver.
•Battery pack included, wall-power optional (sold separately).
•Small, lightweight remote with easy pushbutton.
•Very affordable.
Specifications

Operation Instructions
IMPO TANT: This product must be installed by a licensed electrician. It requires a quick install,
however dealing with 120V AC is VERY DANGEROUS and your warranty will become void if the
EZ-ON is not installed carefully by a qualified technician.
Please note that there are two options for powering your EZ-ON receiver. You may
either use the 4 x AA battery pack (included) which will need fresh batteries periodically
(approx. every 2 ½ months), or you may opt to purchase our EZ-ON Step-Down Transformer
circuit that can convert a powered switch’s 120V AC to 5V DC (sold separately).
Setup:
1. Once your EZ-ON has been installed by a professional, you may now put 4 AA
batteries into the battery pack (follow polarity markings).
2. The EZ-ON remote requires a single 9V battery. Snap on the terminals and attach the
battery to the remote’s battery holder.
3. You’re done Test out your EZ-ON with the pushbutton on the receiver. This should
be done with your electrician around to ensure proper wiring has been executed.
Use the green (ON) and red (OFF) indicator LED’s on the receiver to determine
whether or not it is working properly.
Your EZ-ON should now be working Simply push the button on the receiver or the button on
your remote to toggle your desired appliance on or off. Your remote should have a range of 50+
feet. If it does not, this could be a sign that your 9V remote battery is not fresh.
NOTE: If after some time it is decided that the green and/or red indicator LED’s on your receiver
cause an undesirable glare, you may carefully cut either of them off at the base of their legs
with wire snips. This will NOT damage the circuit, however we do recommend leaving them
attached as long as possible for convenience. If your EZ-ON controls a room’s light, the LED’s
are very convenient because the receiver will glow red in the dark making it easy to find the
pushbutton attached to the wall.

Maintenance
The only maintenance you should need to perform on your EZ-ON is replacing batteries when
they are dead or weak. If your receiver is powered by the battery pack, be sure to replace ALL 4
of the AA batteries at the same time (do not replace only 1).
For safety precautions your EZ-ON receiver is equipped with a 15A fuse to protect the wiring in
your house against fire. This fuse will only blow if your appliance’s original circuit breaker fails,
and therefore under normal conditions should not need to be replaced.

Theory of Operation
Your EZ-ON receiver is constantly running and waiting for input from either its pushbutton or
the remote controller. When the remote button is pressed, the remote emits an Infrared light
pulse of 950 nanometers at 38 kHz. The receiver’s eye sees this pulse and triggers the circuit to
power a relay attached to your appliances wires in the wall. The 38 kHz pulse is condensed to a
single logic high pulse to the 4017 decade counter integrated circuit, which is what toggles the
circuit’s relay between ON and OFF which is attached to an appliance’s switching wires. The
receiver’s manual pushbutton simulates the pulses from the remote to manually toggle the
circuit from the wall.

emote Concepts
The following represents the basic remote circuit, including the equations used to create a 38
kHz signal that pulses the infrared LED. The oscilloscope screen capture shows the pulses at the
capacitor (yellow) and the pulses through the LED (blue).

eceiver Circuit
The above diagram represents the EZ-ON receiver circuit. Each important component is labeled.
The purpose of the RC filter is to combat debouncing of the pushbuttons, and to smoothen any
signals from the remote that may not be 100% clean (i.e., bouncing the signal off of a wall, or a
flickering signal due to a weak remote battery). The purpose of the PNP transistor is to invert
the signal coming from the TSOP (Infrared receiver module). This is because the TSOP’s output
is inverted to begin with (see page below).

TSOP Infrared eceiver
The TSOP382 is what looks for a 38 kHz
infrared light signal from the remote.
This signal must be precisely 38 kHz because the
TSOP382 filters out all other noise (such as from
CFLs) and looks for a burst of 38 kHz pulses.
Basic Characteristics:
Supply Current = 0.27 to 0.45 mA
Supply Voltage = 2.5 to 5.5 V
Distance = 45 m

4017 Decade Counter IC
The following diagram represents the operation of the 4017 decade counter IC.

Optional 5V power supply for receiver (sold separately):
Depending on the configuration of the wall switch, this circuit can be used to tap into the
available 120V AC. This will not work if the appliance was originally controlled by a 1-pole
switch because there won’t be full access to the 120V AC line.
Step down transformer with bridge rectifier circuit.
An LM7805 can be used to regulate a 5V output.
