A modular lamp socket and switch device with fixed switch contacts formed in a ratchet face, and movable contacts in a matching ratchet face cam driven in a snap-acting manner. A turn-knob or a push or pull-type switch assembly provides the cam drive action. Either a one-way or a three-way lamp socket device may be constructed for a turn-knob, push-knob, or pull-chain type using essentially the same components.
