Conductive Keyboard

Conductive Keyboard
Conductive Keyboard & Conductive Buttons, which is a kind of Silicone Rubber Keypad with electrically conductive ink paint. Also known as conductive silicone keyboard & keypads, conductive buttons pads. Silicone Keyboard have some electrically conductive ways: carbon pills & graphite pads, conductive ink printing, metal domes, nickle pills, copper & golden pills.

Different electrically conductive ways have different features and applications.

Rubber Keyboard with Graphite Pads & Conductive Carbon Pills

Graphite Pads, known as Conductive Carbon Pills
Carbon Pills & Graphite Pads main features: Common keypad's conductive ways, Lower Resistance, Stable Performance, Long life time and Cheapest Unit Cost. Rounded Carbon Pills is common
Disadvantage: 

• Conductive Shape Limited

• Resistance Limited: Above 10 Ohms. Common conductive resistance 50-150 Ohms

Electrically Conductive Ink Printing & Painting: 
Features: Common Rubber keyboard Conductive Ways, 
Advantage: 

• Not condutive shape limited,  

• Cheapest Unit Cost.

Disadvantage: 

Resistance Limited, mainly above 50 Ohms (mainly depends on conductive ink materials)

• 
  Metal Domes:
