Filed:
Aug 12, 1976
Appl. No.:
5/713698
Inventors:
Bill F. Helena - Fort Worth TX
International Classification:
G08B 1314
US Classification:
340280
Abstract:
An electrical switch has a switch member having a normally bowed portion adapted to be flattened by a holding member to move an edge of the switch member to a position out of engagement with an electrically conducting member and to move the edge of the switch member to a position into engagement with the electrically conducting member when the holding member is removed and the normally bowed portion is allowed to assume its normally bowed position. The switch is particularly adapted to be used in conjunction with a CB antenna connected to a motor vehicle for sounding an alarm if the antenna is removed.
