摘要：1. A device for mechanically detecting and/or securing the operative position ofelectrical or electronic proximity switches (16), preferably of the kind having magneticcontacts (17a, 17b, ..., 17k) in surveillance equipment and intruder alarms, such switchesbeing disposed on aperture-closing facilities (A, B, ..., K) such as windows, doors, hatchesor the like, the contact part (17) being disposed on one element of such facility, forexemple, on the fixed frame (1) of a window or door, while the triggering part (18) issecured to the other element of the facility, for example, to the sash (2) of the window orthe leaf of the door, characterized by : a support lug (23, 223 respectively) adapted to besecured to one element of the closure facility (A, B, ..., K) for example, to the fixed frame(1) and, disposed adjacent the same on the other element of the facility (A, B, ..., K), forexample, on the sash (2), a catch pin (24, 224 respectively), the lug (23, 223) carrying, atsuch a distance (30, 230 respectively) from the closure plane (31 - 31 and 231 - 231respectively) of the closure facility (A, B, ..., K) as exceeds the response distance of the

proximity switch (16), a stop surface (28, 228) which is disposed in the entry path of thecatch pin (24, 224 respectively) and which merges towards the closure plane (31 - 31 and231 - 231 respectively) into a slot-like or groove-like gate (26 and 226a, 226b respectively)adapted to receive the catch pin (24, 224 respectively), the same being disposed in aguide (34, 36 and 234, 236 respectively) and being adapted to be changed over manually(33, 37 and 233, 237 respectively) in the guide, in a plane parallel to the closure plane (31 -31 and 231 - 231 respectively) between an operative position associated with the stopsurface (28, 228 respectively) and at least one locked position associated with the gate(26, 226 respectively).
