Led Intergrated Emboss Membrane Keypad

Product Introduction

    Jasper has accumulated many years of membrane switch making experience, and most of our people have been in this business for more than five years. We maintains a work force of highly trained engineers who are able to quickly respond to customers differentiate demands for membrane keypad products. 

    Membrane switch has many characteristics, eg light and slim, dust-proof, insulation, anti-shock and easy assemble. By virtue of those features, membrane switch are extensively applied in medical device, industrial control, home electronics, and precise instrument industries etc.
