Product Description

Characteristics:

• Keyboard membrane has good waterproof, dust-proof, oil-proof and anti-corrosion ability. Each key has its own wireline, no matrix code required – just treat these as everyday switches. Matrix cross point switch and can be directly interfaced with serial LCD controller making a complete input output interface. With a removable paper backing to expose a strong adhesive so you can stick this in an enclosure and feed the cable through a slot.
