Both supply and demand are booming, and performance upgrading promotes the development of China's microswitch industry [2016-08-28] -
Chinese suppliers have enhanced the performance of microswitches to improve their competitiveness. The demand from traditional markets and emerging markets is rising, which is expected to stimulate the development of such products in the coming months. Although China's microswitch products are still mainly entry-level and mid-range products, some enterprises are introducing more models with higher electrical and mechanical performance and added value to move towards the high-end market. -
Precautions for use of microswitch [2016-08-28] -
Precautions for use of microswitch 1) When fixing the switch body, please use the small screw M2 on the smooth surface with a torque below 0.098N · m. In addition, in order to prevent the screws from loosening, it is recommended to use washers at the same time. 2) Please note that the action body shall not directly exert force on the button or actuator under free state. When using, the force shall be exerted vertically on the button. -
Type of microswitch [2016-08-28] -
There are many kinds of microswitches, with hundreds or thousands of internal structures, including ordinary type, small type and super small type; According to the protection performance, there are waterproof, dustproof and explosion-proof types; According to the breaking form, there are single connection type, double connection type and multiple connection type. There is also a kind of strong disconnect microswitch (when the reed of the switch does not work, external force can also make the switch open); According to the breaking capacity, there are ordinary type, DC type, micro current type and large current type. According to the use environment, there are ordinary type, high temperature resistant type (250 ℃), ultra high temperature resistant ceramic type (400 ℃) -
Operating principle of microswitch [2016-08-28] -
Microswitch is a kind of quick switch actuated by pressure, also called sensitive switch. Its working principle is that the external mechanical force acts on the action reed through the transmission elements (press pin, button, lever, roller, etc.), and accumulates energy to the critical point, which produces instantaneous action, so that the dynamic 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 action spring produces a reverse action force. When the reverse travel of the transmission element reaches the critical action point of the spring, the reverse action is completed instantaneously.
