Electronic products such as remote controls, industrial keyboards, medical devices, calculators and other small electronic devices have used silicone rubber buttons. Silicone rubber buttons flex a lot of external strength, providing tactile feedback that can be printed on and many other features. The most common feature of a silicone rubber button is the back side of a molded carbon contact pellet. The carbon contact pellet will complete the silicon rubber pressure when the PCB of a circuit is completed. This method of completing a circuit is cost effective and very reliable because it eliminates the need for a mechanical tactile switch.

When the electronic device is operating at low temperatures, the button must also function properly when pressed. These buttons are often made of silicone rubber due to their extremely low temperature resistance. Ultraviolet light is used in many medical devices. Silicone button products are ideal for these devices because of the UV resistance of silicon. The main advantage of a silicone rubber button is its low price. It makes sense to make electronic devices that use these buttons to help keep their production prices low.

This process is used to make silicone rubber products for compression molding and injection molding. Compressed (or vulcanized) silicone rubber enters the chemical reaction and ether sulfur, peroxide, polyurethane crosslinker, metal oxide. In the vulcanization process, the silicone rubber is in the shape of a mold. The injection molded silicone rubber material is forced to heat the barrel and return to the furnace. Then the liquid silicone rubber is pressed down into a cold cavity (mold) to have a certain shape. The material slowly hardens in the shape of a mold as the temperature drops.

The final product of the mold that can be made during the injection molding process is a set of button designs of any size and shape (silicone rubber buttons to make the same mold are not necessarily the same size and shape).
