Original Kailhua – the Story

The kailh Corporation was founded by Mike in 1990. The first push button switches were produced in the Dongguan. From humble beginnings, the company quickly grew in size and reputation after entering the mechanical keyboard market. In the 2015’s, the roots of the kailh family are in Dongguan, hence the company namesake,prosperous = Kaihua. Chinese Entrepreneurship coupled with Chinese Engineering encompasses the history and future of Kaihua. Today, Kaihua is regarded as the epitome of precision, longevity, and responsibility. A unique feeling.

Product Description

A miniature snap-action switch, also trademarked and frequently known as a micro switch, is an electric switch that is actuated by very little physical force, through the use of a tipping-point mechanism, sometimes called an "over-center" mechanism.

Switching happens reliably at specific and repeatable positions of the actuator, which is not necessarily true of other mechanisms. They are very common due to their low cost and durability, greater than 1 million cycles and up to 10 million cycles for heavy duty models. This durability is a natural consequence of the design.

The defining feature of micro switches is that a relatively small movement at the actuator button produces a relatively large movement at the electrical contacts, which occurs at high speed (regardless of the speed of actuation). Most successful designs also exhibit hysteresis, meaning that a small reversal of the actuator is insufficient to reverse the contacts; there must be a significant movement in the opposite direction. Both of these characteristics help to achieve a clean and reliable interruption to the switched circuit

In one type of microswitch, internally there are two conductive springs. A long flat spring is hinged at one end of the switch (the left, in the photograph) and has electrical contacts on the other. A small curved spring, preloaded (i.e., compressed during assembly) so it attempts to extend itself (at the top, just right of center in the photo), is connected between the flat spring near the contacts and a fulcrum near the midpoint of the flat spring. An actuator nub presses on the flat spring near its hinge point
