         Basic Parameter for the Membrane Switch

         Membrane switch is Compositive switch made of insulating material layers and conductive layers. It be   comes  the  first choice for the electric control switch for its unique Superiority. Good appearance, small volum, long life-span  and Bend resistance make the membrane switch popularly accepted. Also, it has strong resistances against the water, fire, oil and scratch. Hereby, the basic parameters of it is presented as follows:

An overview of our off

You are looking for a membrane keypad with an individual and sophisticated design? 

 Our keypads are manufactured to meet our customers` exact requirements – whether in terms of size, design or colour, matt, semi-gloss or glossy, with or without a window, with a tactile action point, including LEDs or other components, integrated in supporting plates or pre-mounted on our enclosures.

And of course, assembly of the membrane keypad is part of our service offer.

 

 

 

  Commonly used controller for membrane switch

  General controller of 2.54 mm and 1.0 mm FPC controller, of course, part of the customer can choose FCI controller or molex controller, Of course, we production depends on the customer's choice

Membrane keypads using conductive silver technology

Of course, we also offer membrane keypads which make use of conductive silver technology. In most cases, our customers like this technology when financial aspects are the main factor. The membrane keypads are manufactured entirely using silk screen printing, so it is easy to create individual designs. It is possible to integrate components with membrane keypads which use conductive silver technology. However, the results are not so sturdy, and are more likely to experience silver migration than when integrated in other keypad technologies. When compared to a membrane keypad with copper-laminated base membranes, membrane keypads which use conductive silver technology can more quickly reach their technical limits when there are applications with many keys (and/or LEDs) on a small area. This is why we always give preference to the use of copper technology.
