Pin on the five-foot touch switch problem Dec 06, 2017

Pin on the five-foot touch switch problem: two pins as a group, the correct pressure to the switch body when the four pin phase conduction, the fifth pin is grounded.

Tactile switch with the development of electronic technology and the development of the fourth generation switch products, the earliest volume of 12mmx12mm, 8mm and 8mm two, now 6mm owed 6om. There are three types of products, vertical, horizontal and horizontal with the ground, and now there are two combinations (3M, 4M, SM, 6M, SM) and potentiometer touch switch combination to meet the domestic requirements of various electronic products . Installation size 6.smm fire 4.5mm, 5.5mm and 4mm and 6mm and 4mm three. Foreign 4.5mm 4.5mm and has a small touch switch and chip tactile switch, chip tactile switch suitable for surface assembly. The current use of conductive rubber switch is also very popular.

Now there are the fifth generation of switch - membrane switch, the same function and touch switch, mainly for electronic instruments and CNC machine tools, but the resistance, feel poor. In order to overcome the phenomenon of poor touch, but also in the membrane switch is not made of silver contact point, but the contact reed.
