Abstract
The switch breaks the current circuit when an access panel or door is opened. It has a switch operating and locking mechanism which cooperates with a key inserted in the switch housing with the insertion or removal of the key used to operate the switch. The key acts on a sliding bolt (16) lying coaxial to the switch operating element (4) and with a locking catch (24) for the bolt (16) only released via the key. The insertion slot (9) for the key extends at right angles to the longitudinal axis of the bolt (16) with a bias spring (18) causing the end of the bolt (16) to project into the insertion slot (9) so that it is pushed downwards as the key is inserted.
