Micro switch principle Micro switch connection method

Microswitch This small electromechanical switch has been developed since the 1930s to meet a variety of different application requirements, including aerospace, home appliances, boiler control, medical equipment, sprinkler systems, testing Equipment, timers, vending machines, etc. Next Xiaobian introduced the principle of micro-switch and micro-switch connection method.

Microswitch principle

The external mechanical force exerts force on the action reed through the transmission element (by pins, buttons, levers, rollers, etc.) and generates instantaneous action when the action reed moves to the critical point, so that the movable contact at the end of the action reed and the constant contact Points quickly turn on or off.

When the force on the transmission element is removed, the action reed produces a reverse action force, and when the reverse stroke of the transmission element reaches the critical point of action of the reed, the reverse action is instantaneously completed. The micro-switch has a small contact distance, a short stroke, a small power, and a rapid on-off. The operating speed of the movable contact is independent of the operating speed of the transmission element.

Micro switch wiring method

Speaking of micro-switch wiring method, it is actually very simple, the general micro-switch has three points, one of the three points is a common point, one is a constant open point, and the other is a closed point, the common point is similar to the socket The neutral line, normally open point, is the point where the current is allowed to flow through the switch, and the closing point is of course the point at which the current passes through. Put the corresponding point into the corresponding position, and it will be fine. Although the method of micro-switch wiring seems simple, but it still requires a prerequisite to do a good job related measures.

Micro switch usage 
The micro switch is very small, but it has a great effect and can be seen everywhere in our lives. Such as computer mouse, car mouse, automotive electronics, communications equipment, military products, testing equipment, gas water heaters, gas water heaters, gas stoves, small appliances, microwave ovens, rice cookers, float equipment, medical equipment, building automation, electric Tools and general electrical and radio equipment, 24-hour timers, etc.

Micro switch type

There are many kinds of microswitches, and there are hundreds of internal structures. There are common type, small size and super small size according to the volume. According to the protective performance points, there are waterproof type, dustproof type, and explosion proof type; according to the dividing form, there are Single type, double type, multiple type. At present, there is also a strong disconnection microswitch (when the switch reed does not work, the external force can also make the switch disconnect); according to the breaking capacity points, there are common type, direct current type, micro current type, high current type .

According to the use environment, there are common type, high temperature resistant type (250°C), super high temperature resistant ceramic type (400°C). The micro switch is generally based on the auxiliary type without auxiliary pressing, and derives a small stroke type and a large stroke type. According to needs, different auxiliary pressing accessories can be added, and various types of buttons can be divided into push button type, reed roller type, lever roller type, short boom type, and long boom type according to the different types of pressing auxiliary switches added.
