IS-2 Interlock Switch for Sectional Door

The IS-2 is an interlock switch for a commercial sectional door. It mounts on the interior side with the included bracket. The switch has a normally closed contact that breaks when the switch is activated. It measures 3 in H x 3 in W x 1-1/2 in D in a steel housing. Wire it into the operator's stop or safety circuit so the door will not run when the interlock is activated, for example when a manual lock is engaged. Use it as a new install or to replace a worn interlock switch.
