A small SPDT (Single Pole Double Throw) slide switch is a type of passive electronic component that allows one input to connect to one of two outputs, making it useful for controlling circuits with a single control point. It typically has three terminals: one common terminal for input and two output terminals for switching between two different circuits.
They can be found in variety of electronic devices from house hold to industrial products. Basically, it is a mechanical component that physically enables or disables the current between wires.
