Abstract
A switch assembly has dual spring biased plungers which operate several switches within a single housing. The dual plungers act independently of one another to provide switch redundancy if required. The plungers have rectangular surfaces with cams, and the switches have cam followers which operate the switches. In an alternative application, some of the switches may be replaced with a printed circuit board and a plunger with multi-finger wiping contacts. The printed circuit board and plunger with multi-finger wiping contacts arrangement allows the switch to produce a signal that is related to the distance of pedal movement. Additionally, a capacitor is provided on the housing for the purposes of filtering any electrical signal produced by electrical contact arching in a switch used in a high voltage circuit. The capacitor is held in the switch assembly by a box and a holding clip. The capacitor's placement in the switching circuit is such that it is in parallel with the switch.
