First, it is recommended to buy a new mouse, maintenance is too much trouble, the ordinary mouse is seven or eight dollars, a little better than a dozen dollars, wireless better hundred eighty.
Secondly, if your mouse is very high-grade, then take it to the electronic city to repair it, the repair price is about ten dollars.
The mouse within the microswitch, is a kind of internal metal reed trigger parts, the mouse button down once, the microswitch within the metal reed with the silver point of the front section of the contact foot below the trigger once, resulting in the circuit conduction to the computer to transmit a signal, and then reset.
All the buttons on the mouse, there must be a micro-switch or a light switch, so in fact, the micro-switch is the mouse button, the mouse shell on the role of the button is just convenient for users to press the micro-switch, nowadays the micro-switch has been more than just for the mouse, but also can be used for a variety of other toys.
There are many kinds of microswitches, and there are hundreds of kinds of internal structures. According to the volume, there are common type, small type and ultra-small type; according to the protection performance, there are waterproof, dustproof and explosion-proof type; according to the form of breakage, there are single-connection type, double-connection type, and multi-connection type. There is also a strong disconnecting micro switch (when the reed of the switch does not work, the external force can also make the switch disconnect); according to the breaking capacity, there are ordinary type, DC type, micro-current type, high-current type. According to the use environment, there are ordinary type, high temperature resistant type (250 ℃), super high temperature ceramic type (400 ℃)
Micro switches are generally without auxiliary pressing accessories for the basic type, and derived from the small stroke type, large stroke type. According to the need to join different auxiliary pressing accessories, according to join different pressing accessories switch can be divided into button type, reed roller type, lever roller type, short moving arm type, long moving arm type and so on various forms.
Micro switch in the need for frequent switching circuit equipment for automatic control and safety protection, etc., widely used in electronic equipment, instruments, mines, power systems, household appliances, electrical equipment, as well as aerospace, aviation, ships, missiles, tanks, and other military fields, has been widely used in the above areas, the switch, although small, but plays an irreplaceable role.
Currently on the domestic market according to the different requirements of the use of microswitches, switch mechanical life of 3W times to 1000W times, generally 10W, 20W, 50W, 100W times, 300W times, 500W times, 800W times, the domestic general use of beryllium bronze, tin bronze, stainless steel wire to do the reed, foreign ALPS can do up to 1000W times, their reeds are made of beryllium bronze, tin bronze, stainless steel wire to do reed, foreign ALPS up to 1000W times, their reeds are used in the same way as the other switches, and they can be used in a wide range of applications. The highest frequency of ALPS can be 1000W times. Their reeds are made of rare metal titanium, and the highest frequency of Tengfei can be 1000W times in China.
Applications
such as computer mice, car mice, automotive electronics, communications equipment, military products, test instruments, gas water heaters, gas stoves, small household appliances, microwave ovens, rice cookers, float equipment, medical equipment, building automation, power tools and general electrical and radio equipment, 24-hour timer, etc.
