Snap action switches are electromechanical devices that are used to detect the presence and duration of any voltage or current in an electrical system, typically in the form of a switch. They can also be used for other functions such as detecting a change in temperature or pressure. The key to the success of a snap action switch is the reliable switching from one state to another within a matter of milliseconds. Snap action switches are commonly known as limit switches.

The 21HE310 is a pole mounted snap action limit switch designed for use in hazardous environments including Class I Division 1 classified areas. It has a delicate mechanical structure which provides reliable yet accurate switching and a single-pole double throw (SPDT) contacts which allows for a wide range of applications. It complies with NEMA standards demonstrating its superior quality and reliability. Furthermore, it is easy to install and requires minimal maintenance.

The 21HE310 works by detecting a change in position along the x, y, and z axes. The device consists of a sensing element with four sensing points in the horizontal direction. When one of these points moves beyond the established limit, the wires inside the body of the switch are severed and the contact is opened or closed. This action is known as a Snap on or Snap off and it occurs relatively quickly and accurately.

The 21HE310 has a variety of applications including industrial automation, such as machine control, packaging machines, process control, and even medical equipment. It is also used in HVAC systems to detect when a boiler or furnace needs to be turned off or on. Finally, the snap action switch is used in the automotive industry for systems such as theft prevention, fuel/brake systems, and pre-start/shut down systems.

The 21HE310 is designed to switch quickly and accurately between two states and therefore has a wide range of applications. It is designed to withstand extreme temperature variations and is suitable for dusty, wet, and hazardous atmospheres. In addition, it is a cost-effective and reliable solution which requires minimal maintenance and is ideally suited to hazardous environments. The 21HE310 can be used to detect a variety of conditions and to switch quickly and accurately between two states, making it an essential element of virtually any industrial automation system.
