ABSTRACT:
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).
