The Kronenberg WZA is a safety switch designed with a positively driven normally closed (NC) contact. It features a transparent cover and an actuator that can be revolved from any direction to ensure safe operation.
Key design elements include an infinitely variable revolving drive head, which provides a large tolerance between contact-making and the stop of the actuator. The device is secured using pressure plates for fixation and offers optional lateral or frontal actuation configurations.
