ABSTRACT:
An electrical circuit controlling device has a housing with snap action means therein adapted for successive discrete snap action movements. Means is movable in the housing for selectively transmitting a force at different preselected levels onto the snap action means to effect the successive discrete snap action movements thereof. An actuating member is movable in the housing and rockably engaged between the snap action member and a pair of switch elements to successively operate them between circuit controlling modes in response to the successive discrete snap action movements of the snap action means, respectively. A method of operating an electric circuit controlling device is also disclosed.
