Abstract

677,376. Switches held set and freed mechanically. BIROME SOC. ANON. COMMERCIAL. &INDUSTRIAL. June 28, 1950. No. 16086/50. Class 38 (v). [Also in Groups XV and XXIV] The circuit between conductors 26 and 27 is alternately closed and opened by a contact member 25 on successive operations of a push-button 18. The button 18 is attached to a plunger b which has a cardioid-shaped groove c therein co-operating with a fixed pin 2 and is acted upon by a spring 1. The groove c has recesses 3 and 12 which are engaged by the pin 2 to lock the switch in the open and closed positions respectively. A by-pass passage 28, 29 from the groove c is provided to enable the device to be readily assembled or taken apart. The groove c may be provided on the guide a instead of the plunger b and the pin on the plunger.
