Introduction to the operating principle of microswitch
Release time:
2023-02-07 12:34
Microswitch is a kind of switch mechanism with small contact spacing and quick action. It uses the specified stroke and force to switch. It is covered with a shell and has a drive rod outside. Because the contact spacing of its switch is relatively small, it is named as a microswitch, also known as a sensitive switch.
Micro switch is also called sensitive switch and quick switch. The pressure drives fast opening and closing, which is used for door opening and closing in the anti-theft system. Microswitch, as the name implies, is a switch with very small force. It is a kind of switch that external mechanical force acts on the action reed through the transmission element to make the static contact and the moving contact at the end of the switch quickly turn on or off. The microswitch has small contact clearance and quick action mechanism. The contact mechanism that uses the specified stroke and force to switch is covered by the shell, and its external part is equipped with a driver, which is compact.
The microswitch is composed of five main parts, with small contact distance and large torque. Generally, there is a drive rod outside.
What is the operating principle of microswitch? Let's analyze it.
The external mechanical force acts on the action reed through the transmission elements (push pin, button, lever, roller, etc.), and when the action reed moves to the critical point, it will generate instantaneous action, so that the moving contact and fixed contact at the end of the action reed can be quickly connected or disconnected.
When the force on the transmission element is removed, the acting reed produces a reverse force. When the reverse stroke of the transmission element reaches the critical point of the reed action, the reverse action is completed instantly.
The micro switch has the advantages of small contact distance, short travel, small pressing pressure and fast switching. The moving speed of the moving contact has nothing to do with the moving speed of the transmission element.
What is the application of microswitch? Let's analyze it.
Microswitch is used for automatic control and safety protection of equipment requiring frequent circuit replacement. It is widely used in electronic equipment, instruments and meters, mines, power systems, household appliances, electrical equipment, aerospace, aviation, ships, missiles, tanks and other military fields. They have been widely used in the above fields. Although very small, the switch plays an irreplaceable role.
At present, the mechanical life of microswitches on the domestic market varies from 3W to 1000W, generally 10W, 20W, 50W, 100W, 300W, 500W and 800W. In China, beryllium bronze, tin bronze and stainless steel wire are generally used as reed, while foreign ALPS can achieve 1000W times, and their reed is made of rare metal titanium.
It can be used for computer mouse, automobile mouse, automobile electronic products, communication equipment, military products, detection instruments, gas water heaters, gas stoves, small household appliances, microwave ovens, electric rice cookers, floating ball equipment, medical equipment, building automation, electric tools, general electric and radio equipment, 24-hour timers, etc.
