"Application: These safety switches are suitable for hinged safety guards, which need to be closed to ensure the necessary operational security. The variety of requirements to be found in practice can be met by means of the wide range of safety switches for hinged guards. Depending on the particular version of the switches, small doors and service flaps as well as heavy hinged doors on engineering machines and plants can be protected in such a way as to provide for easy setting up and maintenance. Design and mode of operation: A general advantage of the safety switches shown here is the integral cam within the safety switch. The requirements of EN 1088, such as positive linkage between cam and actuator as well as protection against tampering are thus fulfilled. This combination within the switch provides cost advantage for the user in avoiding the necessity of mounting a specially designed cam. These safety switches are mounted with slow action."
