A limit switch is an electromechanical device operated by a physical force applied to it by an object

SKU: FTA-48 Categories: ,


Limit switches are an electromechanical device that works when something puts force on them. Limit switches are used to determine if either an object is present or not. These switches were initially employed to establish an object’s limit of travel, hence the term Limit Switch.

What Is the Function of Limit Switches?

Limit switches are electromechanical devices that consist of an actuator; mechanically link to an electrical switch. However, limit switches can be used in a variety of applications. When an object comes into touch with the actuator, the switch activates, making or breaking an electrical connection.

A limit switch serves what purpose?

  • Presence/absence detection.
  • Counting.
  • Range of motion detection.
  • Positioning and trip limit detection
  • When unsafe conditions develop, breaking a live circuit.
  • Speed detection.
Limit switches’ applications
  • Machine tools are things like presses, transfer lines, and special machines. You can use them to make things out of metal.
  • Conveyors, elevators, cranes, and hoists are all examples of equipment used to move things.
  • Machinery for packaging and processing.
  • Textile equipment.
  • Vehicles and lift trucks, as well as construction machines and equipment
  • Cabinets for control.
  • Garage door openers.
Procedure for Connecting
  1. Use a voltmeter to measure how much current a battery can supply. Connect the positive and common terminals in series, as should the resistor.
  2. Attach both LEDs’ negative terminals to the battery’s negative terminal.
  3. In the same way, join the negative (NO) terminal of the limit switch to the positive (+) wire of the green LED.
  4. Attach the plus wire of the red LED to the NC wire of the limit switch.
  • It can switch up to 10A of electricity.
  • It is extremely precise, accurate, and repeatable.
  • It’s a cost-effective sensing solution.
  • Survive the most extreme weather conditions.
  • Uses very little energy.
  • Capable of controlling various loads.
  • The limit switch is little in size.
  • Simple to set up.
  • To activate, it must make physical touch with an object.
  • Wear and tear on the mechanical component is possible.
  • Generally limited to machinery that operates at low speeds.
