FAQ

1. What is function of limit switch?

A limit switch which regulates the electrical circuit to controls the machine and its moving parts. These switches can be used as pilot devices for magnetic starter control circuits, allowing them to start, stop, slow down, or accelerate the functions of an electric motor.


2. What is a limit switch used for?

A limit switch which in electrical engineering is a switch operated by the motion of a machine part or presence of an object. They are used for controlling machinery as part of a control system, as a safety interlocks, position system, or to count objects passing a point.


3. How many types of limit switches are there?

A limit switches are generally composed of five components. The drive mechanism or actuator of the Limit switch is an important part of the Limit Switch and is directly linked to seal performance and operating characteristics. Include plunger, hinge lever, roller lever. manufacturers Omron, Siemens, apt, etc.


4. What is a mechanical limit switch?

A mechanical limit switch is a mechanical device which can be used to determine the physical position of equipment. For example, an extension on a valve shaft mechanically trips a limit switch as it moves from open to shut or shut to open. The limit switch gives ON or OFF output that corresponds to valve position. Normally, limit switches are used to provide full open or full shut indications as illustrated below.


5. Why is the limit switch important?

A limit switches are used in a variety of applications and environments because of their ruggedness, ease of installation, and reliability of operation. They can determine the presence or absence, passing, positioning, count and end of travel of an object.


6. What is the difference between proximity switch and limit switch?

A limit switch is an electromechanical device that is initiated by physical contact of any object using the activator of a switch. Proximity switches or sensors are initiated by a physical presence near them. And physical contact is not necessarily required distance is the main factor determining their operation.
