ABSTRACT:
An electrical switch includes a housing, fixed contact elements fixed with respect to the housing, and movable contact elements movable with respect to the housing. Each of the movable contact elements is positioned directly opposite from a respective fixed contact element. An auxiliary frame is positioned within the housing and has four bearing eyes offset by 90.degree. with respect to each other. Two first pivot pins are offset by 180.degree. with respect to each other and form a first pivot axis. The two first pivot pins are rotatably received by a respective one of a first bearing eye pair of the auxiliary frame. Two second pivot pins are offset by 180.degree. with respect to each other and form a second pivot axis. The two second pivot pins are rotatably received by a respective one of a second bearing eye pair of the auxiliary frame. An actuating member is operable with the first pivot pins and the second pivots pins for moving about the first pivot axis and the second pivot axis from a neutral position to four actuating positions. In each actuating position the actuating member actuates a respective movable contact element causing the respective movable contact element to contact a respective fixed contact element for enabling a corresponding switching function.
