Learn About Limit Switch Applications

If you deal with electrical machinery, then you’ve perhaps come across the famous term “limit switch” before. However, the question is-what exactly are limit switches? And what is the main function of a limit switch? What to keep in mind when purchasing from limit switch manufacturers?

What Is a Limit Switch?

A limit switch is a portion of electromechanical equipment that’s built up of an actuator connected to a sequence of contacts. These contacts let the limit switch notice the presence and closeness or absence of a material or object, generally in manufacturing settings. Depending on what the contact perceives, the sensor shifts an actuator, which in line alters the state of an electrical circuit. This action indicates that some pre-set ‘limit’ has been touched.

Since limit switches mechanically detect pre-set limits, they eradicate the want for manual workers to assess those levels. This alteration makes operating the whole thing, right from heavy machinery to commercial conveyor belts not only much simpler and more accurate but also much more dependable. Therefore, production of limit switch by manufacturers turns out to be more effectual, and work environments become harmless. 

Limit Switch Applications and Functions You Need To Know

Uses of a Limit Switch

Limit switches are habitually utilized for tallying items or resources so that once a limit is touched, the limit switch either closes or opens. This condition is normally the case in engineering applications that comprises of assembly lines. For instance, when the limit switch in a precise part of equipment perceives that it has added a programmed quantity of components to a product, the limit switch shifts the actuator, which in line shifts the piece of equipment away, and the product moves ahead to the next station.

Limit switches can also be utilized as security interlocks to evade machine parts from moving any further when a specific point is reached. A good instance of this is a programmed garage door. Without a limit switch which halts the door once it reaches the bottom rail, the door would continue shifting downwards and ultimately bang into the ground, leading to some serious damage.

Limit switches also find its key usage as part of a greater control system. When a precise limit is reached, the actuator can either de-activate or activate a equipment to avert any sort of malfunctioning or disasters.
