Snap action switches, also referred to as limit switches, are among the most simple and well-known switch actuators. They use a spring-loaded mechanism to open or close an electrical circuit when a force or pressure is applied. Versatile and relatively economical, these switches can be found in many applications across many industries, including automotive, home appliances, and industrial automation.

A snap action switch, as suggested by the name, uses a quick action to open or close an electrical circuit. The precise mechanism is relatively simple. There is a plunger, or actuator, that is spring-loaded and moves inside a body housing. Within the housing, there are two contacts which the plunger can depress. These contacts are separated by a gap. When the actuator is depressed the contacts come into contact with one another, thus creating an electrical circuit. The spring then pulls the plunger back and thus opens the circuit. The snap action that is characteristic of the switch results from the design of both the actuator and the spring. Due to the design, when the plunger is released it is thrown back with considerable force, opening the circuit quickly.

The versatility of the snap action or limit switches comes from the variety of technologies that can be used to detect the actuation. Different actuator shapes and designs, along with a range of materials, make the switch suitable for use in most applications. Nonmetallic actuators are good for use with chemical two-phase liquids, while metallic switches are better suited to high-vibration environments. The wide variety of choices ensures that the right switch can be found for specific conditions and requirements.

Limit switches are also relatively inexpensive, being made up of relatively simple components. In addition, they are also low maintenance and robust so they can perform reliably in harsh environments. All these factors make them ideal for use in a range of industrial applications, from material handling and industrial automation, to process control and motion control.

The versatility of limit switches, combined with their affordability, low maintenance, and robustness, makes them the commonly used actuator for automated systems across different industries. Actuators made for 83802001 are part of this range and perform the same basic task. When the actuator is pressed it opens or closes an electrical circuit. The spring loaded plunger and housing design ensure that this action is quick, providing the robust and reliable switching mechanism required by industry.
