Conductive Methods in Rubber Keypads
- Carbon Pills: Carbon pills are small conductive elements made from carbon-filled silicone rubber. These pills are strategically placed on the underside of the keypad buttons. When a button is pressed, the carbon pill makes contact with the circuit board, allowing the electrical signal to pass through.
- Conductive Ink Printing: Conductive ink is a special ink infused with conductive materials such as silver or carbon. It is printed onto the surface of the rubber keypad, creating conductive pathways. When a button is pressed, the ink traces make contact with the circuit, completing the electrical circuit.
- Metal Domes: Metal domes are tiny metal discs, often made of stainless steel, placed under the keypad buttons. When pressure is applied, the dome collapses, making contact with the circuit board beneath. This contact completes the circuit and registers the keystroke.
- Metal Pills: Similar to carbon pills, metal pills are small conductive elements made from metals like stainless steel. These pills are placed under the buttons and function similarly to carbon pills, allowing electrical signals to pass through when the buttons are pressed.
These methods ensure that the rubber keypad can effectively transmit electrical signals, making them essential components in various electronic devices like remote controls, keypads, and control panels. The choice of conductive method depends on the specific requirements of the application and the desired tactile response of the keypad.
