Program Plan Intro
NO limit switch:
- Normally Open (NO) limit switch refers to a commonly used industrial control device.
- It is used to operate when a predetermined limit is reached.
- It is actuated by contact with an object such as a cam.
- An electrical symbol used to represent NO limit switch is given below
Solenoid:
- The working of solenoid is based on the principle of magnetic induction.
- It contains a coil, frame, and a plunger known as armature.
- The main function of solenoid is to convert electrical signals into
mechanical motion. - Due to its magnetic movement, solenoid is used in different areas such as locking of two devices, interlocking of gear wheel in automobiles and some other medical application.
