The Tactile (Tact) switch is composed of insert, base, shrapnel, button and cover plate. The waterproof Tactile (Tact) switch adds a layer of polyimide film on the shrapnel (as shown in the picture).


The Tactile (Tact) switch has the advantages of small contact resistance, accurate operating force error, diversified specifications and so on. It is widely used in electronic equipment and white household appliances, such as video and audio products, digital products, remote controls, communication products, household appliances, security products, playing equipment, computer products, fitness equipment, medical equipment, note checking pen, laser pen keys and so on.

Introduction: What is Super capacitors ?

Super capacitors, also known as electrochemical capacitors (electric double layer capacitors short as EDLC), gold capacitors, farad capacitors.

EDLC which can hold more than million times capacitance of regular capacitors is the future green energy storage device. Depending on the capacitance, EDLC is able to be variously applied. Less than 1F grade EDLC backs up the data and maintains RTC(Real Time Clock) built in the circuit as an auxiliary power system when a power supply of the application such as mobile phones, MP3 players, and Audio, VCR, etc is stopped. 10F ~ 100F and thousands of F grade EDLC are being used in large hybrid cars, UPS,EMU, copier requiring an instant high power, EDLC is also being gradually expanded to power unit like solar, wind, and environment-friendly renewable energy resources as an essential component.

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval. Please visit our Products page, you could please download all our PDF datasheet and find cross reference for our Trimming Potentiometer and capacitors.
