How to select KCD ship type switch? [2023-03-21] -
Ship switch is also called wave switch and rocker switch. Its structure is the same as that of button switch, except that the handle is changed to ship type. Ship switches are commonly used as power switches for electronic equipment. Their contacts are divided into single pole single throw and double pole double throw. Some switches also have indicator lights, which are called ship switches with lights. Scope of application of ship switches Ship switches are widely used in household appliances. For example, water dispensers, treadmills, computer speakers, battery cars, motorcycles, ion televisions, coffee pots, row plugs, massage machines, etc. in life can be seen in the shadow of boat switches. -
Secret of travel switch [2022-08-27] -
Travel switch. Travel switch is also called limit switch, position switch or end switch. Convert the mechanical displacement signal into electrical signal with the same function as the control button. The contact action relies on the mechanical displacement of the moving parts of the production equipment to collide with the travel switch, so that the contact action can complete the circuit connection or disconnection control. -
The real application of microswitch [2022-08-27] -
It is sufficient to input the travel switch type and replace any damaged parts. If the microswitch is used for a long time, it will inevitably deposit scale. If you want the microswitch to work, you must clean the contacts correctly. The limit switch is used to protect the built-in microswitch from external force, water, oil, gas and dust. The shape can be roughly divided into horizontal type, longitudinal type and composite type. The limit switch mainly includes five parts. -
Five key steps for selecting microswitch [2016-08-28] -
Since its appearance in the 1930s, microswitch, a small electromechanical switch, has been continuously developed to meet various application requirements, including aerospace, household appliances, boiler control, medical equipment, sprinkler system, testing equipment, timers and vending machines. Micro switches are usually used to detect temperature, position and liquid level. -
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. -
Asustek's brain hole is a little big ROG Sica game mouse microswitch is broken, replace it yourself [2016-08-28] -
On the Internet, almost every big brand mouse has someone complaining about the failure of the microswitch, because this small part has to withstand countless clicks every day, and its reliability is always difficult to achieve perfection. Is there any way to solve this problem? Asustek opened its head and thought of a wonderful move: design a slot. If the micro switch breaks, users can change it by hand. -
Don't know inching even after removing the mouse? [2016-08-28] -
There are many kinds of touch switches. In the mouse, we call them "square inching", and the thinner ones are called "patch switches". They save more space than our common long inching, which are common in delicate small mice or side keys. The size of this light touch switch is very small, which can greatly save the space in the mouse. However, we can see that the pin is very different from our common inching. The pressure grams are also hard enough. Our most commonly used Omron D2FC-F-7N pressure grams are 0.74N (75gf), so it is rarely used on common mouse buttons. And we can also see its shortcomings, that is, its life is slightly short, so it can save space and reduce its use frequency by placing it on the button that is not used frequently. -
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. -
Classification of microswitches [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.
