Touch Keyboard Array Matrix Membrane Switch UV and water proof outdoor Membrane Switch Panel with Waterproof grade IP65
A flexible membrane switch consists of printed graphic overlay made from coated polyester film or polycarbonate film underneath layers of circuitry film. The circuit is printed on specially made polyester film for flexible circuitry printed by silver conductive ink by using a screen printing method. The function with electrical contact between the keypad surface and underneath circuits when the symbols on the overlay are pressed. The basic principle of functionality is that the contact behind the tactile key or non-tactile key closes and open loop of the circuit which terminates on the flexible tail. LEDs and resistors can be incorporated easily in this type of membrane switch. The membrane switches are widely used for industrial devices.
With over 20 years of experience, Kaike Electronics is recognized in China as an expert in design, engineering and manufacturing of custom membrane switches. They are screen-printed on polyester and polycarbonate film using conductive ink and UV curable dielectric.
Many of our customers come to us with a vague description of the application. Our engineers work closely with the customers to review the requirements, design the most cost effective solution and manufacture a few proof-of-concept prototypes.
When the customer is satisfied and the design is frozen, we move to a full scale qualification using production equipment and a complete design drawing is submitted to the customer. Upon final approval, the project transitions to production. Kaike Technology offers non-tactile constructions (without direct sensitive feedback) or tactile feeling solutions with metal domes and polydomes, which provide immediate tactile response.
A polydome can be designed (i.e. diameter and height) to meet the actuation force and the switch travel distance required by the application. Metal domes come in different shapes and sizes with actuation forces from 170 to 420 grams and travel distances typically from 0.178 to 0.89mm.
Shielding is available for EMI/RFI protection and ESD discharge.
Single point LEDs and passive components are assembled using low temperature conductive adhesive.
Membrane switches can be customized with embossing. We offer Pillow and Rim embossing but also tiny dimple for visually impaired people.
Our circuits can be terminated with ZIF connectors or Insulation Displacement Contacts (crimped) and black plastic housing. Through-hole printing is also available for double-sided construction.
Coated window lens are incorporated for LCD. It can be clear or color tinted with anti-glare, gloss or matt finish.
Recent developments in light guide material are providing innovative solutions for a uniform backlighting using a limited count of side-firing LEDs and guide foils that are designed to evenly distribute light.
Upon request, our membrane switches can be designed for IP67 environment protection certification.
