Different Types of Limit Switch

What Are The Different Types of Limit Switch?

Introduction A limit switch is an electromechanical device operated by a Manual force applied to it by an object. They are used for regulating machinery as part of a control system to count objects passing a point. A limit switch is an tool that contains an actuator mechanically linked to a pair of contacts. When an object reaches into contact with the actuator, the device operates the contacts to make or break an electrical connection.

Whisker Roller

There are 4 general types of limit switches Lever Plunger

Whisker The whisker switch is a three-inch wire actuator with a micro snap action switch.

On an assembly line or conveyor, whisker switches are typically used as a locating device. If an item is out of place and moves the whisker, the plunger is activated and the micro switch sends an alarm to the operator.

Roller The roller switch is a useful Bit because it has a small lever with a wheel that works as something passes by it. When the lever is pushed in, you can also flip the mode switch to turn it off. To make a fridge light, use the mode with an LED.

Lever Heavy-duty E.O.T. cranes and hoists use lever limit switches to avoid hoisting motion over travel on power and control circuits up to 500 V and 40 Amps continuous current. The limit switch is usually closed and cuts power to the crane's motor to stop it. When the lever is pushed over a projecting member fix, the Lever limit switch operates when it hits a predetermined position.

Plunger Plunger switches need very little physical effort to function. When the plunger is pressed, the electrical circuit is either opened or closed, turning on or off the unit to which it is connected. A spring and a set of contacts are included in each plunger switch, which transform mechanical energy applied to an actuator into an electrical output.

Conclusion Limit switches are electromechanical devices that are activated by an object's physical force. Also Because of their ruggedness, ease of installation, and dependability of operation, limit switches are used in a wide range of applications and environments. I have shown the different types of Limit Switch which will help you to know Limit switches better . Get in touch with a reputed limit switch supplier if you are planning to buy.
