Abstract

224,632. Thompson, J. H. Aug. 27, 1928. Press-button switches with compound movement.-A switch for controlling the movement of a pointer by means of a series of electromagnets comprises a disc q' pivoted to a base and having a pivoted handle r. The base carries a number of fixed arcuate contacts q. The pivoted disc q<1> carries a spring blade contact q<2> which is moved into engagement wth the fixed contacts by one or other of the cam surfaces r<2> on the handle r, when the disc q' is rotated. Upon release of the handle r after a movement of the disc q<1> to select any particular fixed contact q, the spring blade contact q<2> moves out from engagement with the fixed contact and so breaks the circuit. Specification 225,493 is referred to.
