Safety Limit and 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.
Dozens of configurations are available.
