ABSTRACT:
A switch has a housing (11), a pair of switching units (17, 18) with buttons (19) that can be depressed to operate each switch unit, and a rocker (23) pivotally mounted on the housing to pivot clockwise and counterclockwise from a neutral position. An elastomeric diaphragm (30) mounted on a top wall (12) of the housing, extends across an aperture (13) in the housing, with first and second lower parts (28, 29) of the rocker passing through the diaphragm to rest closely above the buttons on the switch units. The diaphragm not only largely seals the switch units, but biases the rocker towards the neutral position.
