Abstract: An exemplary circuit arrangement for a belt lock of a passenger restraint system in motor vehicles includes one contact sheet pair having a fixed contact sheet and an elastic contact sheet which interacts with a slide. The slide is a component of a locking mechanism located in a belt lock housing for an inserted belt tongue, and is pushed in a displacement channel from a first end position into a second end position when the locking mechanism is actuated. The contact sheet pair is in a housing part which borders the displacement channel. A part, which projects from the elastic contact sheet through a housing wall opening into the displacement channel, is exposed to the action of the slide to open or close an electrical contact to the contact sheet. The circuit includes means for preventing abraded matter from traveling into the contact region of the contact sheet pair.

The switching contact part can have at least one extension that projects over the outside surface of the mounting plate in the operating position. When the switching contact part is exposed to pressure in the direction of the mounting plate, an electrically conductive contact between the switching contact part and the fixed contact part can be interrupted or established. A fixing device can be included via which the switching contact part is pretensioned in such a way that the extension does not project over the outer surface of the mounting plate. The fixing device can be detached when the switch arrangement is being mounted with release of the elastic switching contact part.
