A toggle switch has a toggle pivotably mounted in a threaded boss of the switch case. The toggle is preferably translucent so light from an internal lamp can reach the top of the toggle. A sleeve is slidably received on the toggle and has an inner end that is shaped to cooperate with an upper end of the boss to define discrete toggle positions. A spring biases the sleeve into a locked position engaging these shaped end portions.
