Micro switches are with tiny contact spacing And snap-action mechanism, a contact mechanism that performs switch action with a specified stroke and a specified force, covered with a shell, and a switch with a drive rod outside. Because the contact distance of the switch is relatively small, it is called a micro switch. Also known as sensitive switch, snap switch. Press-actuated quick switches. For door switches in anti-theft systems, etc.
Micro switches are available in a wide variety, with hundreds of internal structures According to the volume, there are ordinary, small and ultra-small; according to the protection performance, there are waterproof, dust-proof, and explosion-proof; according to the breaking form, there are single, double, and multi-connection.

Micro switch structure
Micro switches have fine contact spacing and snap-action structure, and the contact structure of the switch posture is developed with the required stroke arrangement and force. Covered by the casing, there are actuators outside, and the design is small.
1 and 2: The raw material used for the top and bottom covers is PBT30%GF
3: The key material is PBT30%GF
4: The raw material of the converter is beryllium bronze
5: The raw material of the spring piece is beryllium bronze
6: The raw material of the support frame is copper
7: The raw material of the NC terminal is red copper
8: The raw material of NO terminal is red copper
9: The raw material of the terminal is silver aluminum alloy
10: The raw material of the conversion film is silver aluminum alloy

Micro switch principle:External mechanical force passes through transmission elements (pressing pins, buttons, Lever, roller, etc.) act on the action reed, and when the action reed is displaced to the critical point, an instantaneous action occurs, so that the moving contact and the fixed contact at the end of the action reed are quickly connected or disconnected. When the force on the transmission element is removed, the action reed generates a reverse action force, and when the reverse stroke of the transmission element reaches the action critical point of the reed, the reverse action is completed instantaneously.
Micro switches are used to carry out automatic control systems and safety maintenance in machinery and equipment that need to be frequently connected to power circuits, and are used in electronic products, instrumentation equipment, mining, power supply systems, electrical products, electrical equipment, as well as aerospace, aviation Companies, warships, cruise missiles, meat tanks and other defense industries have long been used in left and right industries. Although the switch is small, it has an irreplaceable effect.
At this stage, the micro switches in the Chinese market are different according to the application regulations. The service life of the mechanical equipment of the switch varies from 3W times to 1000W times, usually 10W, 20W, 50W, 100W, 300W, 500W and 800W times. China usually uses beryllium bronze, tin bronze and stainless steel wire as reeds. Overseas ALPS can guarantee a maximum of 1000W times. Their reeds are made of non-ferrous metal titanium.
It can be used in such as computer mouse, car mouse, automotive electronic products, communication equipment, military products, testing equipment, natural gas water heaters, gas stoves, small electrical appliances, microwave heating, rice cookers, floating ball machinery and equipment, medical machinery, building automation, Pneumatic tools and general electrical equipment and cordless telephone equipment, 24-hour timers, etc.
