Waehleinrichtung fuer das Steuersystem einer automatischen Vorrichtung

摘要

Sequential operation of an automatic machine is controlled by an assembly of binary switches which are selectively operated by a selector member. Plunger operated microswitches may be used in conjunction with a selector member comprising a stiff apertured plate so that when the plate is pressed against an assembly of switches, it depresses the plungers except the ones located against the apertures and thus makes the selection. Lever-operated microswitches may alternatively be used in conjunction with a selector member having a profiled edge which is shaped to engage some levers and not others when it is brought into operational relationship with the switch array.
