Switches, Buttons, and Relays

The Pololu RC switches make it easy to turn devices on and off with a standard hobby radio control (RC) system. Several versions are available, ranging from one with a simple digital output to modules with integrated MOSFETs, relays, or multiplexers.

These electrically operated switches make it possible to control circuits with low-power signals while offering electrical isolation between the controlling circuit and the circuit being switched.
