Brackets

Every bracket on this page exists for one reason: holding a limit switch in the right position relative to the door. A limit switch that moves, even slightly, drifts out of adjustment and the door starts over-traveling or stopping short. We stock mount brackets in two profiles plus a cam strike bracket, and we fabricate custom brackets when your door needs something else.

Which bracket does what

The mount bracket and the strike bracket are not alternatives. One holds the switch, the other is what the switch reads. A complete installation usually needs both.

Standard mount or flat mount

The difference is depth. The standard mount bracket stands the switch off the mounting surface by roughly an inch and a half, which is what you want when the switch needs to sit proud of the door face to reach its actuator. The flat bracket is an eighth of an inch thick and slightly longer, for installations where there is no room to stand the switch off and the actuator geometry still works flush. Measure the clearance you have before ordering, because a standard bracket in a tight spot will foul on the door and a flat bracket in the wrong position will leave the switch out of reach of the cam.

Why the strike bracket matters

A limit switch actuator is a wear item, and what it strikes determines how fast it wears. Our cam strike bracket is shaped to give the actuator a controlled approach rather than a hard square hit, which extends the working life of the switch itself. If you are replacing limit switches more often than seems reasonable, the strike surface is worth looking at before you blame the switch.
