ABSTRACT:
Limit switch, particularly for use as a lock switch for safety belts, composed of a flat housing, spaced contact elements in the housing, a switching lever formfittingly secured on one side of the housing with the other side free to move, a spring-loaded switch element on the free end of the lever to open and close the contacts, the side wall of the housing acting as a stop to limit movement of the lever, a cover with an opening for the housing, and a tripping pin attached to the lever extending through the opening, which pin is activated by for example closing a seat belt by a sliding tongue inserted in the housing thus moving the switch element to open or close the contacts.
