ABSTRACT:
A rocker switch assembly for controlling at least one fluorescent lamp has a contact mounting block fitted in a housing, with a pair of normally closed contacts at one end of the block and at least one pair of normally open contacts at the other end. A rocker button is supported in an opening in the housing above the contacts on the mounting block for limited vertical and pivotal motion against spring biasing forces while being restrained against longitudinal movement. A preferred support means includes stub shafts extending laterally from each side of the rocker button that fit slidably in vertical bearing slots on each side of the opening in the housing. A spring detent catch mounted at the one end of the housing for interfering engagement with a protrusion on the adjacent end of the button provides a positive snap action between a horizontal or neutral "lamp on" button position and a tilted "lamp off" position in which the one end of the rocker button is depressed to open the pair of normally closed contacts. In an oppositely tilted momentary "lamp start" position, the other end of the rocker button is depressed against a biasing means to close each pair of normally open contacts.
