Electric Motor Limit Switch

These switches can be used as pilot devices for magnetic starter control circuits allowing them to start stop slow down or accelerate the functions of an electric motor.

Electric motor limit switch.

I would like to install 2 limit switches 1 to stop the motor when going up at a certain point and 1 to stop the motor when the lift reaches the bottom. In electrical engineering a limit switch is a switch operated by the motion of a machine part or presence of an object. Must make direct contact with target. Moving mechanical parts will wear out.

The few electric car electric window systems i ve looked at don t have limit switches. They do have a controller for each motor that senses the current. The controller keeps the voltage applied for maybe 1 2 second then shuts off the motor. Limit switches can be installed into machinery as control instruments for standard operations or as emergency devices to prevent machinery malfunction.
