发明名称 Flexible switch contact having a precious metal contact surface
摘要 A switch mechanism designed to overcome the problem of electrical noise employs a compound movable contact assembly, including a coil spring member and a smooth-surfaced wire contact member mounted thereon. The flexing of the coil spring provides an advantageous rolling, wiping motion for the wire contact member, without the noise-producing electrical discontinuities associated with earlier mechanisms in which the coil spring itself made direct electrical contact.
