Abstract
Abstract A multiple-switch arrangement wherein a battery of momentary and/or latching switches is mounted in a control panel and the inner end portions of switch housings have transversely extending channels for a centrally located tubular receptacle and two lateral control rails. The inner end portions of the housings carry adapters for blocks of microswitches which are actuated by motion transmitting posts secured to plungers which are reciprocable in the housings and can be depressed in response to displacement of knobs installed in the outer end portions of the housings. The posts which register with the receptacle can extend through the receptacle on their way into engagement with movable portions of the respective microswitches and thereby displace blocking members which are installed in the receptacle and serve to prevent simultaneous actuation of microswitches associated with two or more housings.
