In today's world of the automation industry, limit switches and sensors play a vital role. A limit switch is an electromechanical device composed of an actuator connected to a range of contacts. The movement of a mechanical component or the presence of an object activates a limit switch. When an object contacts the actuator, the limit switch operates to make or break an electrical circuit.
The terms normally open (NO) and normally closed (NC) are employed to describe the states of switches. Limit switches are available in various configurations, including NO (Normally Open), NC (Normally Closed), and some limit switches with a combination of the two NO plus NC.
Some Commonly Used Limit Switches In Today's Modern Industry
- Top End Plunger Limit Switch
In this type of limit switch, the mechanical force is from the side.
- Side Plunger Limit Switch
In this type of limit switch, the mechanical force is from the side.
- Steel Roller Plunger Limit Switch
In this type of limit switch, the mechanical force is given by 35 Degree CAM from the side.
- Thermoplastic Roller Lever Switch
In this type of limit switch, the mechanical force is given by 35 Degree CAM from the side.
- Adjustable Thermoplastic Roller Lever Switch
In this type of limit switch, the mechanical force is given by 35 Degree CAM from the side and the roller height is adjustable.
- Steel Rod Lever Limit Switch
In this type of limit switch, the mechanical force is given by the moving part from side and the rold height is adjustable.
- Cat’s whisker Limit Switch
In this type of limit switch, the mechanical force can be applied from multidirectional.
All the plunger-type and the cat's whisker limit switches work for mechanical linear movement applications. And all the lever-type limit switches work for mechanical rotary movement applications in automation industry. Cat's whisker limit switches is a multidirectional switch.
