DEFINITION

Classification: 200/61.66

(under subclass 61.64) Devices in which (1) a substitute implement or the like, not intended for use with the lock, or (2) the mere insertion of an implement (key) or substitute therefor causes the circuit to be made.

(1) Note. The unauthorized keys of section (1) under this subclass definition do not, of course, serve as operators for the locks or bolts; however, those which are proper operate to move the latch or lock-bolt without changing the circuit condition then present.
