Limit switch: A limit switch is an electromechanical

A limit switch is an electromechanical unit that consists of an actuator that is connected mechanically to the set of contacts. When the object travels towards and comes in touch with the actuator, the limit switch performs the contacts to make or break an electrical connection. Product definition Limit switches are a type of sensor that detect presence and absence. Specifically, mechanical limit switches are switches that are mechanically activated, meaning that they have some sort of arm, lever, knob, plunger, etc., which is physically—or mechanically—activated by making contact with another object. We will start by having a look at what they actually are, how they work, where we use them, and also the different types of limit switches . So let’s get into in, what is a limit switch ? A limit switch is an electro-mechanical device that is operated when an external force is applied to it. Working Principle of Limit Switch The use of limit switches that can be activated by the motion of the machine is required for the automatic operation of that machine. A limit switch converts the mechanical motion of the machine into an electrical signal that can be used to switch circuits. The operating position of the limit switch is where it transitions from its normally opened (NO) or normally closed (NC) state to its operating state. The release position is the point at which the ...
