“Micro switch is a very sensitive switch. To operate require very less force and also they also acquire very less space in installation. Most of the time they use only in a space-restricted area. (Space Limited).
The switch consists of a spring lever for making the closed circuit. It is known as an actuator. The device is called an actuator. Its design includes a spring that applies force to make contact and then returns to its original position upon release.
Micro Switch
In make-or-break contact applications, an actuator spring-based lever operates Micro Switches. When the user pushes the lever, it activates contact with the circuits. Releasing the button lever brings back the lever to its actual position, opens the circuit, and breaks the contacts.
Furthermore, microswitches use metal contacts which makes them suitable for a variety of applications such as industrial, home appliances, automobiles, and electronics equipment.These devices have gained recognition for their high reliability, cost-effectiveness, low maintenance requirements, and long lifespan.
Furthermore, microswitches employ metal contacts which make them suitable for a variety of applications including industrial, home appliances, automobiles, and electronics equipment.
- Basic Micro Switches:- The switch has a lever to operate by pressing with little force contact to make a close electrical circuit after clicking. The switches regain their normal position.
- Limit Switches:- It is a type of micro switch to detect the presence the present or absence of an object by mechanical physical contact with the switch.
- Roller Switch:-The roller type of limit switch detects the mechanical presence of material in moving equipment. It finds common use in lifts, conveyors, and other similar applications.
- Snap-Action Switches:- It is the most common type of switch-hinged “lever” or “plunger” to press the click sound and after the click regain the normal position.
- Double Pole Micro Switches:- In have more advantages to using this we can double pole contact use for the single time press and close both of the double poles in a single instance of time.
- Sealed Micro switches:- This switch is used for the seal from the sealant with dustproof and waterproof for. The applications like industrial, outdoor, and dusty environments.
Working on the Micro Switch
The working of the lever or plunger required minimum force to press and make contact close to the electrical circuit. Open or close the circuit by using a spring-based lever.
The minimum millimeter movement in the lever for the movement of the lever makes the contact of the electrical circuit close or open. The major advantage id quickly responds in a millisecond and makes a “click” sound by the button and again reaches natural conditions.
Application of the micro switch.
- Momentary limit switch for controlling the movement of the lift.
- Tracking the conveyor movement by using the roller limit switch.
- The physical movement type of the basic limit switch used inside the industrial electrical panel for door lightning.
- The tracking of the movement of the object by physical contact with the object.
