Product Overview
The Micro Limit Switch Long Hinge Roller 28mm from Pro Tronix combines the reach of a long lever with the smooth operation of a roller tip. The roller is specifically engineered to handle lateral force, allowing objects to slide over the switch without causing mechanical binding or damage. Featuring an SPDT (Single Pole Double Throw) configuration, this 3-pin switch provides maximum flexibility for your wiring needs, whether you require a “Normally Open” or “Normally Closed” signal.
