Working Principle

The 21HE23-RB snap action, limit switch works by using a spring-loaded plunger to sense the position of the switch. The plunger is actuated by a plunger, which is connected to the plunger’s movable head. When the plunger moves, it pushes on a stationary, circular disc, which is connected to the contacts of the switch. The disc is then held in place by a spring, so when the plunger moves, it pushes the circular disc, which in turn pushes against the contacts of the switch. As the disc is pushed, the contacts of the switch open or close, depending on the direction of the movement.

The 21HE23-RB snap action, limit switch is designed to provide high reliability and performance, as well as a broad range of temperature and operating ranges. It is designed for a wide variety of environmental conditions, including wet, dry, and high or low temperature environments. It is also designed to be compliant with a variety of industry standards, and it is UL, CSA, and CE compliant.
