Membrane switch

These are membrane switchs which are customized based upon the required design crafted to highly perfection.Its a make of flexible circuit board which is UL approved and Rohs compliant.

The top overlay is as designed as the customer requirement with n number of buttons. The buttons are of two varities, which are tactile and non tactile.

The operations of these buttons is 100000 and this feature is availaible in feather touch mode also.

MEMBRANE SWITCH OPTIONS
There are a number of options within a membrane switch as described below
 
TEXTURING
The graphic overlay is textured in either matt or gloss and a range of custom finishes in between. A matt textured finish is most common. Windows can be printed in the matt polyester to allow clarity for LCD and LED displays and the windows can be tinted in a variety of colors.
 
TACTILE DEVICES
Metal domes are tactile devices that are inserted within the membrane switch to give a physical tactile response when pressed (Clicked). They can be designed as part of the circuit or above the circuit. A range of sizes are available. An alternative to a metal dome is a polyester domes which is created by permanently forming one layer of the membrane into a dome shape.
 
BACKLIGHTING
Backlighting is frequently seen in many devices. There are a number of ways to do this however the most effective are Electro luminescent Backlighting (EL) and woven fibre. Jasper can do EL-embeded membrane switch with perfect combination technique.

RFI SCREENING
Radio Frequency Interference (RFI) is a major factory which industry engineer considered, and also legally restricted in many countries. Electronic equipment must be protected from unanticipated behavior caused by RFI and Jasper Electronics has developed specialist solutions in this area.
 
SURFACE MOUNT DEVICES
It is possible to incorporate surface mounted devices such as LEDs and resistors with the membrane switch. This may save allow costs savings in PCB design while allow flexible placement of the PCB
