Abstract

1,140,951. Locks. F. W. COVENEY and B. M. HASTINGS. 6 Sept., 1967 [6 June, 1966], No. 25015/66. Heading E2A. [Also in Division G4] A lever tumbler lock 1 is .provided with a micro-switch 15 connected in an alarm system (see Division G4). The contacts 13, 14 of the switch are normally closed via contact 11 by means of protector 2 being pivoted about pivot 3 to contact stop 10. An unauthorised attempt to open the lock causes protector 2 to rotate to the position shown, thus opening contacts 13, 14 to actuate the alarm.
