Bolt switch contacts are suitable for monitoring door locking. The bolt switch contact has to be fitted into the frame striking plate in such a way that it is activated by the deadbolt. The signal can be evaluated or displayed in equipment such as alarm systems, building monitoring systems, visual and acoustic signal generators, etc.

Due to the closed design of the housing, the dead bolt cutout is closed at the back as a special feature for steel frames and profiles. The profile interior is not visible. This dead bolt switch contact is first to be installed on the striking plate, then the striking plate has to be fastened to the frame.
