Membrane switch mounting and operation

►The right way to mount membrane switch

1)Clean up the surface where the switch is bonded and make sure it is flat ,without rust, oil and dust.
2)Compare the size to membrane switch where need be stick ,check if position is correct.
3)Tear off 10mm length of the bottom release paper from side.
4) Put the tail through the back board. Please do not pull the tail with force. The minimum bending radian of the lead wire is R=2mm. The hold edge must smooth in case of damaging the tail.
5)Align the panel with the sticking place and press on the fixed part, then slowly remove the rest release paper and flat the panel.
6)The stick process is finished in one time.Switch can not be repeated stick.
Please make sure the bending angel of panel is lower than 15 degree when sticking.
7)Please do not pull the connector so hard when in connection. For female connector, please hold the house when in connector.Do not pull the lead wire directly. For FPC( Flexible printed circuits) structure, please unlock the socket before plugging.
Note:To assure the switch life , please put it on the table flatly when testing the hand feeling. Do not pinch the button when holding it on hand.

 

►Operating guidance of membrane switch

Working Environmental Requirements
1-1.Operating temperature:
Metal dome :-20℃-60℃
Poly dome:-20-40℃
1-2.Operating Humidity:
Ordinary membrane switch:40℃,RH <90%

Waterproof membrane switch:  IPX5

 

Mount Requirements

1)The membrane switch is suitable for clean and smooth surface, such as ABS,PC and stainless surface. It don’t fit for silicon surface (adhesion promoter needed).

2)Operating temperature: 15-30℃
Operating Humidity: RH45~80%
3)The bond process is one time operation. The switch can not be repeat bonded, or it will affect the stickiness of adhesive and the lifespan of buttons.

4)Gently assemble the switch and do not pull the tail hard. The minimum bending radian of the lead wire is R=2mm.

Operating on keypad
1)The membrane switch should be used on flat and hard surface to press keypad. Do not press it on soft or curving surface or pinch it on hand. Wrong operation will short the lifespan of switch and also will cause damage.
2)Please press button by finger or soft silicon. Do not use hard objects like screwdriver, metal stick in case of any malfunction.Don’t knock button by heavy objects.
3)Do not use sharp objects to poke any areas on the panel or knife to scratch it.
4) Use the product under required environment.
5)Do not use the normal panel membrane switch (without water proof and ultraviolet proof) outdoor for long time.

 

Electrical requirement
Working Voltage:  

Silver printed circuit membrane switch: 30V MAX
FPC/ PCB membrane switch: DC 50V

Work current: 
Silver printed circuit membrane switch: 30mA MAX(depend on the trace width and component on the circuit)
FPC/ PCB membrane switch: 1A MAX

 

Storage conditions
Temperature: 0-30℃
Humidity: 10%<80%
Void direct sunlight; keep it sealed.
Do not squeeze the switch and keep it flat.
