KFC-045P3-H Tactile Switch Working:

KFC-045P3-H is an on/off electronic 4.5*4.5 tactile switch working that is only on when the button is pressed or if there is a definitive change in pressure.
It was used for circuit board, there are many different kinds of height for the switch:3.8, 4.3, 4.8, 5.0, and 7.0mm.
The Tactile Switch applications include: Low power, miniature devices, digital switching, anything where operator feedback is required (a switch confirmation coming from the switch being depressed) will find that the perfect choice is a Tactile switch.
