A receptacle switch having a center-off position, momentary-on position, and maintained-on position. The switch includes a housing with a toggle, a first stationary contact, a second stationary contact and a third movably contact, and a leaf spring therein. The toggle has a cam member which engages a cantilever arm supporting third contact to hold third contact spaced between the first and second contacts in center-off position. The cam member also controls movements of the third contact from its center-off position, to maintained-on position, and to its momentary-on position. The leaf spring selectively engages a first notch in a bottom portion of the toggle to maintain the toggle in the off position, or engages a second notch in the bottom portion of the toggle to maintain the toggle in the maintained-on position, or engages a smooth portion of the bottom portion of the toggle to momentarily maintain the toggle in its momentary-on position until the toggle is released.
