Limit switches are mechanical or electrical switches that are designed for sensing for a certain hydraulic or electromechanical reference position and generating control signals. Snap action limit switches have a variety of specific applications where a reliable, and repeatable operation is desired. The D2D-1102 is an example of a snap action limit switch that can be used in several different applications.

What Is a Snap Action Limit Switch?

A snap action limit switch is a type of switch which has a unique design that enables it to operate quickly and precisely. This design involves a snap-action contact, which is a reversible, self-actuating part with a spring-loaded plunger. The plunger moves rapidly when triggered, either closing or opening the circuit or signaling a change in position. The action is initiated by the user, either directly by moving a plunger or actuator, or indirectly by introducing a voltage or supplying current to the switch. Other forms of actuation, such as mechanical or thermal, can also be used to trigger the switch.

Advantages of Snap Action Limit Switches

Snap action limit switches benefit from the fast, precise action that is responsible for the name. The short travel distance of the plunger means that contact points can react quickly and accurately to a range of triggers. Additionally, the materials used to make the switches are often resistant to many types of corrosion and wear which can increase the lifespan of a switch. Switching forces can also be highly reliable, as multiple sma ll contact points can maximize fail-safe performance and provide further protection against wear and tear.
