in recent years, with the traditional market and emerging market demand continues to rise, the domestic demand is also rising demand, micro switch as a type of switch, the demand is also increasing with the market.

    microswitch definition and working principle of the micro

    switch is with small contact separation and fast moving mechanism, with stipulation stroke and force of switch moving contact action mechanism, covered with a shell and the external a driving rod of a switch, because the switch contact spacing is relatively small, named micro switch, also called sensitive switch.

    external mechanical force through the transmission element (according to the pin, a button, a lever and a roller) will force on the reed motion, when the reed motion displacement to the critical point to produce instantaneous action, reed motion at the end of the moving contact and the fixed contact quickly switched on or off.

    when removing the force transmission component, the reed motion produced reverse acting force, when the transmission element reverse stroke to Reed's critical operating point, instantaneous complete reverse action. The contact distance of the micro switch is small, the action is short, the power is small, the power is small, and the switch is fast. The movement speed of the moving contact has nothing to do with the speed of the driving device.

    microswitch application range

    fretting switch is mainly used in the gas stove, microwave oven, electric rice cooker, such as a computer mouse, electronic equipment, car electronic products, military products, test instruments, medical equipment and other modern industrial products also have microswitch figure. In addition to

   , the micro switch is also integrated into the sprinkler, water pipe system, industrial equipment and some PC and peripherals. Aviation and automobile industry of the product is also very interested in aircraft, aircraft, tanks, turnstiles and an electronic parking brake actuator are the main application.

    suppliers at home and abroad competition for the market and frequent movements

    application widely stimulated the inching switch the major supplier to the market's desire, both domestic suppliers and foreign giants are peeking into this huge market.

    Honeywell (Honeywell), OMRON (Omron), Alps and Burgess and other overseas manufacturers in the high-end market share. Still, local businesses are full of confidence in the coming months. For example, the crown of Huizhou is expected to grow by 50% this year, to maintain the growth rate in 2010. Yueqing Sanxiong Electric Co. is expected, its export revenue and shipments will exceed last year's level. In order to cope with the growth of the situation, manufacturers have to purchase new automatic equipment and increase foreign trade personnel.

    local micro switch to enhance the performance of the

    even though the Chinese micro switch products are still based on entry level and mid-range products, Chinese suppliers have enhanced the performance of the micro switch to improve competitiveness, but some companies are launching more high electrical and mechanical performance and added value of the model, forward to the high-end market.

    current R & D work is mainly to improve the durability of the product, improve the rated current and voltage, reduce the operating force and extend the product life. In terms of product life cycles, are generally higher than 1000000, the enterprise's goal is to increase to 200 to 3000000 times. Huizhou crown Thai Electronics Co., Ltd. G5 series of control force can be as low as 15gf, rated current up to 26A, suitable for high power devices.

    at the same time, these manufacturers are also improving the product's waterproof, explosion-proof, dust and high temperature resistance, and the use of metal sealing. In particular, Shenzhen Xing Yi Sheng Electronics Co., Ltd. also launched a LED display with the switch, you can demonstrate animation and other effects.

    summary:

    in a massive invasion of imported products, we are pleased to see the rise of domestic suppliers, with the technology and capital investment, the future of local manufacturers will usher in a better development opportunities, to win more market share.
