Electrical Mosquito Racket Swatter with Torch

As we know the common membrane switch is usually use PET and PC film as the graphic overlay. The product can be very thin, usually less than 1mm. 

But sometimes many customers design their product to be rubber keypad switches. Because of that rubber can give users a very good touch feeling. 

In addition, rubber keypads can make carbon pills on the backside of the buttons, the carbon pills are conductive, then it can be combined with PCB circuit 

very easily. We only need make the gold plated conductive pads on the PCB, then assemble the rubber keypad with PCB, when you press the buttons, the 

carbon pills will connected to the gold pads, then trigger function.

The rubber keypad switches also can achieve the backlighting easily. As we know the rubber raw material usually is translucent. It is light through. After painted we wanted colors on the rubber, we only need laser etch the backlit symbols and letters, then the LED light from the backside of PCB or membrane circuit can be through the etched area out to get the backlit effect. 

Rubber is easy to clean, so once the keypad is contaminated you can clean it very easily. Rubber keypad's press life also is very high. At least 1,000,000 times above. It is very durable and not easy damaged. So the rubber keypad switches are widely used in machinery, industrial manufacturing, vending machine, dirty and oil contamination environment and others.
