Parallel guide mechanism for a switch

摘要

A parallel guide mechanism includes a peripheral housing and a central mass, for accepting a mechanical input from a user, located within the peripheral housing. The central mass moves responsive to the mechanical input. A first beam and a second beam horizontally separated by a gap and substantially located in a first plane extend from a first vertical surface of the central mass and connect the central mass to a first inner vertical surface of the peripheral housing. A third beam located in a second plane is vertically spaced apart from the first and second beams and is horizontally positioned in the first gap between the first and second beams and extends from the first vertical surface of the central mass and connects the central mass to the first inner vertical surface of the peripheral housing.
