Keypad Conduction

Keypad Conduction & Keyboard Conduction, known as Button Conduction, which as a switches components, have many conductive ways, like carbon pads & graphite pills, conductive ink printing, metal domes, nickle pad, copper pills & gold pads.

Different keyboard conduction ways have different features and applications.


Carbon Pads & Pills, known as Graphite Pads
Black Carbon Pads 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. 



Electric Conduction Ink Printing: 
Features: Common keyboard's Conductive Ways, 
Not condutive shape limited,  Cheapest Unit Cost.
Disadvantage: Resistance Limited, mainly above 50 Ohms (mainly depends on conductive ink materials)


Metal Domes: 
Features: Lower resistance, Common keyboard's Conductive Ways, 
Disadvantage: Bad Tactile Feel, Without Dust Free Functions


Copper & Golden Pills
Features: Lowest Resistance, Stable Performance, long life time. 
Mainly used in Automobile Products
Disadvantage: Lower Production Efficiency, Expensive Unit Cost


Nickles Pills & Pads
Features: Lowest Resistance, Stable Performance, long life time. 
Mainly used in Automobile Products
Disadvantage: Expensive Unit Cost
