The lifespan and tactile feel of the disassembly patch light touch switch are determined by the combination of the stroke and spring of the light touch switch. The shorter the stroke, the lighter the sound, and the longer the lifespan. The longer the stroke, the opposite is true. In a fixed spring process, the lifespan of the patch light touch switch is mainly determined by the stroke or sound; In addition, the key factor determining the lifespan of the shrapnel is still stamping technology. Previously, stamping technology from Japan and Taiwan has been quite popular in China, so with the improvement of technology, whether to further reduce the requirements for imported materials.

The material of the shrapnel is the main factor affecting the long service life of the SMD touch switch. The materials of the shrapnel include steel shrapnel, iron shrapnel, circular shrapnel, square shrapnel, and silver copper shrapnel. For example, the lifespan of 250GF shrapnel in the market mainly includes four types: about 50000 cycles (domestic phosphor copper or relatively backward stamping technology), about 100000 cycles, and over 200000 cycles (stainless steel)

There are three types of packaging for SMT patch touch switches: SMT patch packaging, bulk manual plug-in, and DIP plug-in tape packaging. The packaging problem is graded from fast to slow assembly and manufacturing speed, and we hope that entrepreneurs cannot be trusted.

Touch switch is an electronic switch that can be turned on by lightly pressing the switch button. When releasing the hand, the switch is turned off,

The structure of the light touch switch consists of: insert, base, spring, button and cover plate. The waterproof light touch switch adds a layer of polyimide film on the spring.

Regarding the pin connection method of the five pin patch light touch switch: two pins are grouped together, four pins are used for more stable welding, the fifth pin is used for grounding wire, and the other two are contact on/off terminals.
