Overview：
The fundamental operation of a carbon pill keyboard revolves around its unique method of conducting electricity through carbon pills. When you press down on the soft silicone surface of the keyboard, the surface compresses, causing the conductive pellet to make contact with the PCB. This contact establishes an electric current, which is essential for the keyboard’s functionality. Essentially, the carbon pellet acts like a miniature resistor within the circuit, with its resistance value affecting the keyboard’s sensitivity. Carbon pills are typically composed of a mix of silicone and carbon, which allows for flexible design possibilities. As a result, these pills can be shaped into various forms, including round, oval, or rectangular, depending on the design requirements. The adaptability of the carbon pill’s shape underscores its versatility in keyboard design.

How To Use Carbon Pills：
- Smooth Matte Carbon Pills: With a smooth and matte surface, these pills are typically used in applications requiring low friction and stability, such as precision switches or high-end electrical contact points. They help reduce wear and enhance reliability.
- Textured Carbon Pills: The surface texture with small grids increases friction and contact stability. These pills are suited for applications requiring higher friction or anti-slip properties, such as switches or buttons, providing better grip and tactile feedback.
- Low Resistance Conductive Graphite Pills: With a resistance of less than 10 Ohms, these pills offer excellent conductivity and are used in high-performance electronic devices and applications requiring low-resistance connections, such as high-frequency signal transmission and sensitive electronic component contacts.
- Common Resistance Carbon Contacts： With a resistance of less than 50 Ohms, these pills are suitable for most standard electrical contact applications, such as ordinary switches and low-power circuits. They provide adequate conductivity and stability but are not ideal for applications requiring very low resistance.
