The light touch switch, also known as the key switch, first appeared in Japan [called: sensitive switch]. When it is used, it presses the operating direction of the switch to meet the conditions of the operating force. The switch function is closed and connected. When the pressure is cancelled, the switch is opened. Its internal structure is realized by the force change of the metal spring.



Tap switch



The tap switch is an earlier volume of 12mm × 12 mm, 8 mm × 8mm, now 6mm × 6 mm. There are three types of product structures: vertical, horizontal and horizontal with ground terminal.

In foreign countries, there are two types: 4.5mm small and chip 1. The chip is suitable for surface assembly. The light touch switch has the advantages of small contact resistance, accurate operating force error and diversified specifications. It has been widely used in electronic equipment and white household appliances, such as audio-visual products, fitness equipment, medical equipment, digital products, toys, computer products, household appliances, security products, money detector, communication products, etc.
