This high-voltage switching module is the "electronic successor" of the conventional mechanical servo driven switch. Designed for high loads and voltages, loads such as pumps can be switched on and off conveniently via the transmitter and receiver. It is also suitable for interruption of the glow plug circuit in gas engines. The module is connected to an output of the receiver and switches the voltage of your load's external supply battery on and off via the joystick or switch of the transmitter.
