Contact arrangement for electrical monitoring of entrance doors - has lever moved by door lock or latch which slides permanent magnet past reed contact on PCB

The contact arrangement has the contacts located in the door frame. They are activated by the door latch and/or door lock and by virtue of the switch position, indicate the state of the latch and lock. The contact housing (1) has a PCB (printed circuit board) (3) with at least one reed contact (2). There is at least one pivoted lever (4) which can move a sliding rocker arm (6) with a cam. In the rocker, there is a small permanent magnet (7). The end of the lever (4) touches, and is moved by, the latch or lock of the door. As the magnet (7) is slid along, so it changes the switch position of the reed contacts (2). ADVANTAGE - Easy to assemble, requires little space and hermetically- sealed contacts are contamination-proof.
