Limit Switches

A G Systems Controls offers Limit Switches used in material handling equipment to stop or limit the movement of the over-head cranes, bucket elevators, conveyor belt, etc. These heavy-duty limit switches can be mounted at the head and the tail end of the equipment, where its movement is to be stopped. The travelling equipment stops when the projecting flag hits the actuating lever handle of the lever switch. The operating lever gets actuated at 45-degree angle on either side, and the state of the contact changes over to stop the motor. The operating lever automatically resets to normal position. On the reverse movement of the equipment, the operating lever is self re-setting type. These limit switches can be mounted in horizontal as well as vertical position. Housing: limit switches are available in strongly built, robust housings specially designed, keeping in mind the various applications and the hostile site condition.
