Conductive keyboards, also referred to as conductive buttons or pads, are a type of silicone rubber keypad featuring electrically
conductive ink paint. They offer various methods of electrical conductivity, including carbon pills and graphite pads, conductive
ink printing, metal domes, nickel pills, copper, and golden pills. These keyboards are known for their versatility and reliability in
a wide range of applications.
 
Various methods of electrical conductivity exhibit distinct characteristics and are suited for different applications.
 
Conductive Carbon Pills


Rubber keyboards featuring graphite pads and conductive carbon pills are commonly known for their conductive capabilities. The
main features of graphite pads and carbon pills include lower resistance, stable performance, long lifespan, and cost-effectiveness.
However, they also have limitations, such as restricted conductive shape and resistance levels typically above 10 ohms, with
common conductive resistance ranging from 50 to 150 ohms.
 
Electrically Conductive Ink Printing & Painting


Electrically conductive ink printing and painting offer common conductive ways found in rubber keyboards. They come with
advantages such as non-conductive shape limitations and the lowest unit cost. However, they also have limitations, with resistance
levels typically above 50 ohms, primarily determined by the materials used in the conductive ink.
 
Metal domes


Metal domes provide lower resistance and utilize common conductive ways found in keyboards. However, they come with the
disadvantage of offering poor tactile feedback and lacking dust-free functionality.
 
Rubber Keyboard with Copper & Golden Pills


Rubber keyboards with copper and golden pills offer the advantages of the lowest resistance, stable performance, and long lifespan.
They are primarily utilized in automobile products. However, they come with the disadvantage of lower production efficiency and a
higher unit cost.
 
Rubber keyboards with nickel pills and pads


Rubber keyboards with nickel pills and pads feature the advantages of the lowest resistance, stable performance, and long lifespan.
They are predominantly utilized in automobile products. However, they come with the disadvantage of having an expensive unit cost.

 
In conclusion, conductive keyboards offer a versatile and reliable solution for various applications, thanks to their different methods of electrical
conductivity. Whether utilizing carbon pills, electrically conductive ink printing, metal domes, or copper and golden pills, each approach presents
its own set of advantages and disadvantages. Despite these limitations, conductive keyboards remain indispensable in industries requiring
durable and efficient input devices. As technology continues to evolve, further advancements in conductive keypad designs are expected,
ensuring continued innovation and performance excellence in the field.
