Selector switches are actuated with a rotary knob or lever of some sort to select one of two or more positions. Like the toggle switch, selector switches can either rest in any of their positions or contain spring-return mechanisms for momentary operation. To understand the principle of operation of the selector switch, three lamps are provided and all are fitted on a Bakelite panel. Selector switch select only one lamp from three of them.
