What the Limit Switch Does

Commercial operators use limit switches as part of the travel-limit system.

As the operator reaches its programmed mechanical limit, the limit mechanism activates the switch, signaling the control system to stop or change the appropriate operating function.

A damaged or worn limit switch may contribute to symptoms such as:

• Operator failing to stop at the correct position

• Inconsistent open or close limits

• Door traveling beyond the intended stopping point

• Intermittent limit operation

• Operator stopping unexpectedly

Other components in the limit assembly can cause similar symptoms, so proper diagnosis is recommended before replacing the switch.

Important Compatibility Information

Before ordering, verify:

• Operator manufacturer

• Exact operator model

• Existing limit switch part number

• Electrical rating

• Switch configuration

• Limit-system design

Do not select a replacement limit switch based only on appearance.

Installation

Disconnect electrical power before servicing a commercial operator.

After replacement, the operator limits and safety systems should be inspected, adjusted, and tested before returning the door or gate to normal operation.

Commercial overhead doors and gate operators contain powerful moving components and electrical equipment. Installation by a qualified technician is recommended.
