The activation threshold and direction are configurable, and a safe-start feature reduces the likelihood of unexpected activation. This assembled version ships with the 5V relay, terminal block, and straight male header pins soldered in, so it can be integrated into hobby RC systems without the need for additional soldering. The included power relay is an Omron G5LE-14-DC5 and is rated for up to 10 A under most conditions.

This product consists of a single-pole, double-throw (SPDT) power relay and a control circuit that measures incoming radio control (RC) signals, making it easy to control large, electrically isolated loads in RC systems. Example applications include using extra channels on an RC receiver or servo controller to turn on lights, motors, or irrigation valves. The RC switch is available pre-soldered or as a partial kit that allows for greater application flexibility:

The RC switch measures the width of incoming RC pulses and compares it to a user-configurable threshold (with ±64 µs of hysteresis) to decide whether to activate the relay. By default, the threshold is approximately 1700 μs, with switch activation occurring above the threshold (longer pulses), but the switch has a learning mode that allows you to change the threshold and the activation direction. A safe-start feature reduces the likelihood of unexpected activation.
