In the remote control industry, what is the role of the structure of the silicone button

Conductive silica gel is a kind of silicone rubber that contains special conductive particles that are continuously extruded or molded into silicone buttons. Conductive silica gel buttons are one of the buttons of many electronic products, and they are mainly used for conducting electricity.

A part of the conductive surface silicone button has a conductive function. When the silicone button is pressed, the conductive surface contacts the switch contact on the circuit board. At this time, the switch is closed. When the silicone button is released, the conductive surface separates from the switch contact, and the switch opens at this time. , (The conductive materials are mostly conductive inks and conductive carbon particles for silica gel buttons). Features and applications of remote control silicone key products.

​

1. High temperature resistance: the applicable temperature range is -40 to 230 degrees Celsius, and can be used in microwaves and ovens.

2. Easy to clean: The silica gel products produced by silica gel can be cleaned after being rinsed in clean water, and can also be cleaned in the dishwasher.

3. Long life: The chemical properties of the silicone material are very stable. The products made by the silicone keys have a longer life than other materials.

4. Variety of colors: different beautiful colors can be deployed according to the needs of customers.

5. Environmental protection and non-toxic: no toxic and harmful substances are produced from the raw materials entering the factory to the finished product shipment.

6. Electrical insulation performance: Silicone rubber has a high resistivity, and its resistance can remain stable in a wide temperature range and frequency range.

Exhaust slot When the silicone button is pressed, the air under the inclined wall is removed from the exhaust slot so that the silicone button can be pressed. When the silicone button is released, external air flows from the exhaust slot into the inclined wall below, and the button can Bounced smoothly.

The oblique wall of the button can determine the position of pressing and rebounding the silicone button. Its inclination angle, shape and thickness directly determine the load, feel and elasticity of the silicone button.
