Conveyor Pull Cord Safety Stop Switch
4B Pullswitch

The Pullswitch is a failsafe taut wire emergency pull cord stop switch for conveyors. PVC-coated steel pull wires and pigtails connect between the switches to provide easy installation and continuous emergency stop access along the length of the entire conveyor.  

Pullswitches can be installed at 200-ft intervals, reducing overall system cost. Quick location of a tripped switch is provided by a standard reflector or optional flag marker, and the tripped signal can be wired back to an indicator panel or PLC.  

The Pullswitch’s IP65/NEMA 4, 4X, 9 rated enclosure is made from polycarbonate and stainless steel, making the housing corrosion resistant and weatherproof. A total of six independent changeover contacts inside the Pullswitch offer unique operation and control. Two independent cam operated switches with snap action mechanical operation are provided for conveyor shutdown, and four additional micro-switches signal for a slack wire alarm.  

The Pullswitch is CSA class II division 1 groups E, F, and G approved.
