Sequential switching assembly having plural, spaced flexible contact
layers
摘要:
A multiple switching apparatus comprising two spring-like switching members disposed in a tandem array with each integral with its metallic support base. The central area of each of the switching members is defined by a plurality of slots formed in the support base with the length and displacement of the slots defining the force-displacement characteristics of each switching member and, accordingly, of the tandem array. The top switching member moves downward until it produces a first switching function, with further movement of the top switching member effecting movement of the second switching member such that a second switching function is produced.
