Membrane Switch

Operating voltage:

Membrane switch Advantage: 1. Pleasing in appearance, innovative and 2. Small size, the thickness of thin, light weight, more conducive to the notebook computer keyboard light, thin, short, small and high-intelligent direction. 3. Moisture-proof, dust-proof, anti-oil pollution and harmful gases, sealing strong earthquake acid and basic resistance. 4. Long life, bending resistance.
