Snap Action Limit Switches

83170902.SP.LEVIER is a snap action limit switch with a wide range of applications. Using its mechanical snap action, this switch is reliable and easy to use. Limit switches can be used in a variety of devices such as security systems, HVAC systems, motor control systems, lift systems, and factory automation systems. They are used to detect the position of moving parts and to limit the travel of actuators.

Principle of Operation

The 83170902.SP.LEVIER is a single pole, single throw (SPST) snap action limit switch that can open or close a circuit similarly to an ordinary switch. It is designed to operate in an environment exposed to extreme temperatures and require minimal maintenance. The internal structure of the switch consists of two metal contact points joined by an arm. When an external force is applied to move the arm, the contact points are forced together. This causes the electrical connection to be made, thus completing the circuit.

When the force is removed, a spring-like action causes the arm to move back to its original position. This causes the contact points to be forced apart, thus breaking the electrical connection. This action is what is referred to as snap action, because it occurs quickly, much like the snap of a finger.

Applications

The 83170902.SP.LEVIER can be used as an override control to allow for manual control in the event of a power failure. It can also be used to detect the presence of an object or to limit the travel of a mechanism. It is ideal for applications where reliability and durability are crucial such as in the food processing industry, waste management systems, and industrial machinery.

The limit switch is also well-suited for hazardous environments where there could be flammable materials, combustible dust particles, or sparking. It is also useful in applications that require precise timing such as safety systems and motor control systems.
