Abstract

An optical detecting arrangement for detecting movement of relatively movable parts 5, 7 to or from predetermined relative positions comprising light emitting means 1 associated with one of the parts 5 so that when the light emitting means 1 is energised the light emitted is transmitted through light transmitting means 10 associated with the other of parts 7 when the parts are located in the aforesaid predetermined relative positions whereby the transmitted light is received by light receiving means 2 associated with the one part. The detecting arrangement is especially applicable to security systems for doors, windows, safes, etc. in such applications the emitting means may conveniently be modulated and the receiving means output synchronously detected, both being attached to a fixed member. The arrangement may be used as a switch, wherein an optical path is made or broken by operation of the transmitting means. <IMAGE>
