Publication number: 20120262257Abstract: An apparatus (1) for monitoring the state of a protective device (2) of a machine (4) in particular is a safety switch for monitoring the closed state of a protective door or the like. The apparatus (1) has a switch housing (22) with a switch head (24) and an actuator (8). In the closed state of the protective device (2), the actuator interacts with the switch head (24) and, as a result, the closed state of the protective device (2) can be signaled. The apparatus (1) has a tumbler device (20) with a tumbler element (30) mounted movably in the apparatus (1) and by which the closed state of the protective device (2) can be locked releasably. The tumbler device (20) has at least one permanent magnet (34).Type: ApplicationFiled: June 5, 2012Publication date: October 18, 2012Inventors: Erik BÄCHLE, Walter LINK

Patent number: 6989727Abstract: A locking system is for a safety switch. The switch has a reading head (2) and an actuator (3) with first and second modules (10, 14) containing electric and/or electronic components. The components can be caused to interact electrically in a contactless manner to control the safety switch. The actuator (3) can be locked on the reading head (2) by a controllable electromagnet (7), which cooperates with a counterelement (12). The counter-element (12) and/or the electromagnet (7) is/are connected in a fixed manner to a corresponding base element (13), which is fixed to the actuator (3) or reading head (2), but can be pivoted in relation to the base element. The first and/or second module (10, 14) is/are integrated into the respective counter-element (12).Type: GrantFiled: September 17, 2002Date of Patent: January 24, 2006Assignee: Euchner GmbH & Co.
