Abstract
A multiple cantilever spring contact switch has a base, a housing and a cap. A plurality of pairs of contacts are mounted in the base and the housing fits over the base and contacts. A cap is mounted for movement up and down on the housing and has a plurality of cam members which extend through slots in the housing aligned with the contacts. The cap is resiliently biased upward, and downward pressure on the cap moves the cap downwards and the cam members slide down the slots and actuate one contact of each pair. The contact pairs can be normally open or normally closed, or combinations thereof, and actuation of the one contact by a cam member changes the condition of the contact pair.
