Snap Action, Limit Switches are used in a multitude of applications due to their ability to make quick, reliable contact changes in response to operating conditions. It has become an industry standard for its robust design, reliability, and accuracy.

A limit switch is a type of switch that operates at distinct positions in a user-defined range. These switches help to protect operators from hazardous working environments and robotic machinery from overloading. In addition, they hold a variety of mechanical, environmental, and electrical specifications.

The working principle of snap-action, limit switches is based upon a snap-action spring, referred to as a "pawl," that works in tandem with a plunger. When the plunger is pressed in, the pawl\'s movement causes the position of the switch to change. The result of this switch can be two- or four-position depending on the type of pawl used within the switch.

Limit switches are used in a variety of applications in industry and commercial settings. Many industrial machines incorporate limit switches to prevent damage and guarantee safe operation. In these cases, limit switches can be used to detect if a specific position has been exceeded or if a component has reached its minimum or maximum value. In HVAC settings, limit switches are used to control the maximum and minimum temperatures to ensure that the desired settings are reached.

Limit switches are also used to detect when components have exceeded their recommended load, as well as to detect when an area of a machine has moved too far. In these cases, the switch can detect when a certain set of measurements are not met and shut down the equipment to avoid damage. They can also be used to monitor the location of parts on a conveyor belt and detect if an item has fallen off the belt.

Limit switches are a reliable and effective tool for controlling various operations in industrial settings. As their demand has grown, the availability of different types of switches has increased, allowing for greater customization and application. Snap-action, limit switches are a popular choice due to their reliable, accurate operation and long lifespan.
