LEDs Backlight Rigid PCB Circuit Membrane Switches

LEDs Backlight Rigid PCB Circuit Membrane Switches VTMS00044

What is the LEDs Backlighting Rigid PCB Circuit Membrane Switch? It means that the membrane switch's circuit layer is rigid PCB and assembled SMD LEDs on PCB circuit. PCB can be 1 layer or 2 layers for membrane switches application. In addition on PCB circuit also can assemble other SMD or PTH components and even assemble bolts and screws. VTMS00044 is a kind of PCB circuit membrane switch used on outdoor detecting instruments. It consists of top antiscratch PET graphic overlay and rigid PCB. The buttons are embossed with tactile metal domes.

Details of Flex & Rigid Membrane Switches

The circuit of membrane switches can be flex and rigid. It depends on the customer end application and also related to the cost budget and other considerations. For example, life, resistance, connection type on main board etc.

For the flex circuit membrane switches, there are two types. They are silver printed PET circuit and copper etched FPC circuit. Their difference and advantages&disadvantages listed bellow:

Items	Silver Printed Circuit	Copper Etched FPC Circuit
Material	PET (Polyester)	Copper
Conductor	Printed silver	Copper
Contact Fingers	Silver and Carbon	Gold plated
Contact Buttons Pads	Silver	Gold plated
Life & Reliability	normal	good
Stability	normal	good
Resistance	low	Very low
Cost	low	high
Lead Time	2-3 days	7-10 days
Pitch	0.5mm (not suggested), 1.0mm,1.27mm,2.54mm	0.5mm, 1.0mm,1.27mm,2.54mm

> Membrane Switches Design Factors

To make a quotation of the membrane switch need the following information:

1) Vectograph drawing, like CorelDraw, Ai, CAD drawing;

2) If no drawing, then we need know the following information:

2.1) How many colors on the graphic overlay layer?

2.2) How many buttons? Are the buttons need embossing or not? Need metal domes or not?

2.3) How many LEDs on the circuit?

2.4) Product outshape size?

2.5) Tail(circuit cable) lenth?

2.6) What kind of connector do you want? Female, male or ZIF? If need female and male connector, how many PINs?

3) If have an original sample it also will be good. We can copy the sample to design the engineering artwork drawings. As to the material and components that you are not familiared with, it doesn't matter, we can suggest the proper material as per our experiences.
