Abstract

706,630. Retractive switches. BURNDEPT, Ltd. April 1, 1952 [May 21, 1951] No. 11822/51. Class 38(5) [Also in Groups XXV and XL(c)] An on-off switch for use in a portable radio receiver comprises a stirrup-shaped member 36 to which is attached an insulating plate 37, silver-plated contact members 38 passing from one side of the plate through the plate 37 and thence through apertures in the member 36. A bridging member 41 which is supported by a spring 39 normally connects the two contacts 38. The switch is mounted within the receiver which is of the type having a lid held by a sliding stay, and is so positioned relatively to the stay that when the lid is closed the tip of the stay depresses the bridging member 41 to open the switch.
