The Wireless Control System from CARTEK is the quickest and easiest way to install pushbutton controls to a detachable racing steering wheel.


The system has 8 pushbutton switches which are wirelessly linked to 8 relays within the Relay Control Unit. These relays are microprocessor controlled and individually configurable to provide a choice of functions including momentary, latching and flashing modes for uses such as: PTT radio, pit lane limiter, dash menus, lights, indicators, etc.


The complete system includes a universal fitting steering wheel panel, incorporating 8 sealed pushbutton switches and infra red transmitter module, an infra red receiver and a relay control unit.


The infrared Transmitter module is mounted to rear of the Steering Wheel Pushbutton Panel and is battery powered. The Transmitter only consumes electrical power when a pushbutton is pressed and therefore does not need to be turned off when not in use.


When a pushbutton is pressed an LED on Transmitter will show the status of the internal battery. If the LED shows Green then the battery is in good condition, if the LED shows Red then the battery needs to be replaced.


Channel mode configuration:


Each channel can be individually configured to perform any 1 of 5 different functions:
Mode 1: Momentary action
Mode 2: Latching (without memory)
Mode 3: Latching (with memory)
Mode 4: Flashing (slow speed, minimum 5 seconds)
Mode 5: Flashing (fast speed, minimum 3 flashes)
Mode 6: Flashing (slow speed, latching)

It is also possible to alter which pushbutton is allocated to which channel. Full reset function is also available.


The Wireless Control System can be mounted to most racing and aftermarket steering wheels.


It now comes a multi coloured vinyl pack and UV Fluorescent vinyl pack (glow in dark under UV light) allowing full customisation of the steering wheel.  


Cartek uses Infrared to communicate between the Steering Wheel and Control System.

By using this technology the wireless communication is completely protected from outside signals such as radio waves and EMF unlike other systems on the market. The system also allows the wireless link to be full 360 degrees.


The fast response time of the Cartek Wireless Control system mean that we have been able to produce a version for paddle shift race cars. Two of the eight channels have been reserved for the paddle shift, whilst the other six are completely configurable. The paddles are manufactured out of Carbon Fibre, making it an extremely light weight solution.
