Industrial safety – Safety Interlock Switches

Safety Interlock Switches

Safety interlock switches respond when a mechanical guard opens. Interlock switches feature “positive opening” contacts for high reliability regardless of environmental conditions and withstand attempts to override the switch and defeat the system.

mGard
mGard is the premier range of module robust trapped key interlocks for heavy duty applications. Trapped key interlocking is a tried and tested method of mechanically safeguarding dangerous machines and hazardous processes, and is suitable for use up to SIL 3 (EN/IEC 62061), Category 3 and PLe (EN/ISO 13849-1). It is called “Trapped Key” as it works by releasing and trapping keys in a predetermined sequence. After the control or power has been isolated, a key is released that can be used to grant access to individual or multiple doors.
