What Are Light Switches And How Do They Work?

Did you know that probably not even one day has passed when you have not seen or used a limit switch? Yes, it is true. Limit switches are extensively used in residences, offices, etc. The history of limit switch traces back to the early 1900s. It is a kind of electromechanical switch that provides a limit or stop the movement of an object as soon as it reaches the preset position. They have the property to automatically detect the existence of objects nearby. They can also identify if the moving boundary of the object has been crossed. 

Like its name, this device marks the limit or the end beyond which the object cannot travel and hence is stopped by this particular tool. A switch is employed to control and monitor the movement. 

How Do Light Switches Work?

A standard light switch widely found in industrial setups comes with a mechanical actuator connected to a string of electrical contacts. Whenever an object, often called a target, physically touches the actuator, it results in causing movement in the actuator plunger. This leads the electrical contacts to turn on or turn off their electrical association. 

Light switches rely on the mechanical development of the actuator plunger to manage and modify the state of the electrical switch. Other similar equipment like inductive or capacitive proximity sensors or photoelectric sensors also performs the same function without contacting the object. Thus, light switches can be called contact sensors, which contrast to other general proximity sensing devices. Light switches are usually mechanically operated and come with heavy performing contacts that can switch higher currents.

What Are The Components Of A Light Switch?

Light switches are an assembly of actuators that are fitted with operating heads. It also has switch body mechanisms and a network of electric terminals that help connect the switch to the electric circuit responsible for limiting. 

The operating head of the actuator makes linear, perpendicular or rotary motions which are then interpreted by the actuator to turn the switch on or off. The switch body houses the switch contact apparatus, which is monitored by the actuator. Electrical terminals are linked to the switch contact, allowing the wires to be connected to the switch using terminal screws. 

Owing to the mechanical and performance parameters of the various machines, features like size, operational power, mounting mechanism, and stroke rate are crucial for the setting up and maintenance of limit switches. Another key element that should be considered is that the electrical rating of a limit switch should complement the mechanical system loads, which it will be limiting. This ensures prevention of instrument failure. 

What Are The Benefits Of Light Switches?

Light switches offer many benefits that are innate to their arrangement. Some of them are:

  • Their layout is extremely simple.
  • They can be easily used in several industrial setups.
  • They are accurate and offer good repetition.
  • They consume less power.
  • They are used to handle multiple loads.
  • Their installation is quite simple.
  • They are very reliable. 
  • They are robust and durable.
