Limit switches are an essential component of any gate opener system. These switches are responsible for communicating with the motor to stop it from moving the gate too far in either direction. When the cam or lever reaches the limit switch, it triggers the switch to close, which then sends a signal to the gate motor to stop.

It’s what lets the garage door opener know when the door is completely closed and stops the motor automatically. For swinging or sliding gates found in facilities such as office buildings, apartment complexes and parking garages, a limit switch automatically tells the gate when to open and when it’s fully closed, thus deactivating the motor.

For the swing gate opener, a limit switch can stop the actuator from exceeding an extended or retracted length. Adjustable limit switch is designed to stop the actuator at a predetermined point during extension or retraction, which allows you to set the travel limits in accordance with your needs.
