When the Switch button of the silicone membrane switch is pressed from above, the angle web will be deformed to produce the tactile feedback so that the bottom carbon dots, silver dots, and gold dots will contact the bottom PCB, PET, or FPC conductive dots. And then, the product function can be realized. When the pressure is released, the Web will recover, the conductive particles will separate from the line, and the closure will be cancelled. If the rubber membrane buttons have no conductive particles, the bottom of the rubber keypad switch is likely to have shrapnel as the conduction point. Compared with carbon dots, silver dots and gold dots have lower resistance and are more used in medical applications.

Applications for silicone rubber keypad membrane switches:

Medical devices

Industrial equipment

Marine

Agricultural

Health & Fitness Equipment

Defense

Why is rubber popular?

Excellent physical and chemical properties: cold and hot fatigue resistance, excellent weather resistance, excellent moisture resistance, ozone resistance, antibacterial and ultraviolet radiation performance, long-term outdoor use without cracking. Super-stretch does not deform and has a strong resistance to pressure.

Price concessions: The unit price of rubber membrane buttons is lower, but the cost of molds is higher. After the mold is completed, the product delivery time is faster. Suitable for mass production

Design for silicone rubber keypad membrane switches:

Niceone-tech can change the Web of silicone rubber buttons, switch travel, and the hardness of silicone rubber to achieve different Tactile feedback.

Key surface treatment: The surface of silicone rubber can be changed by spraying touch oil or PU to achieve different touch feelings. At the same time, the spraying of PU and feel oil can make the button logo and font on the silicone rubber more wear-resistant and increase the service life. The method of glue application makes the button logo and font on the silicone rubber not only beautiful but also more wear-resistant

According to the application area of the product, Niceone-tech, a leading membrane keypad manufacturer selects one or more non-conductive rubber, snap dome, or conductive pellet as the conduction point according to the situation.

The custom silicone rubber keypads can be designed into different shapes.

Rubber membrane switch graphics can use screen printing to customize different color patterns and logos.

If different colours are needed for the same rubber membrane buttons and flow molding the color in the compression molding process is used in the silkscreen.

The backlight needs to use the form of laser engraving to form the area to be illuminated, and select the metering lamp to illuminate. Laser etching generally removes the outer coating and leaks the lighter-coloured coating below. At the same time, PU should be added to the outer coating to make the laser engraving process more beautiful.
