SIlicone Rubber Keypad Hotbar Lamination PCB Membrane Switch

Silicone Rubber Keypad Hotbar Lamination PCB Membrane Switch LTMSZYN0039

LTMSZYN0039 used the hotbar lamination technology for the flexble FPCcable laminated on to the rigid PCB. This technology need use ACF heatseal machine which is mainly used for those keypad which need assemble the flexible cable to rigid board or flexible cable to flex board and no need use ZIF connector. This keypad also has a silicone rubber keypad which wraping the border of the PCB for waterproof purpose.

> Rubber keypad Membrane Switches = Rubber Keypad + Membrane Switch

Silicone rubber is an excellent choice for device operation controls. It is soft and elastic. It can give user a very nice touch feeling. In addition rubber is also have the following features and benefits:

• Excellent resistance to both heat and low temperature (-55℃ to 250℃);

• Minimum noise generation due to soft and elastic contact structure;

• Minimum abrasion and high resistance to SO2 and oxidation even in heavy humidity;

• Water and contamination resistant

Cosmetically appealing, 3-D Rubber Keypads offer the reliability of a membrane or PCB-substrate switch, with the three dimensional look and tactile feel of a silicone rubber keypad for a variety of applications including medical, industrial and commercial products.

> Why need rubber keypad switches?

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.

> What types of rubber keypad switches there are?

1) Rubber keypad + silver printed PET circuit;

2) Rubber keypad + copper flex FPC circuit;

3) Rubber keypad + PCB circuit;

4) Graphic overlay + rubber keypad + PET/FPC/PCB circuit;
