Overview
What is a membrane switch?
A membrane switch is a common component of applications used across 
many sectors, from consumer electronics and industrial environments to 
medical and military applications.
✓ Installing a membrane switch correctly is critical to make the most 
out of your investment. 
✓ In this presentation, we go over every single installation step to 
ensure that your engineers don’t accidentally damage the switch 
while installing it in your unit.

Step 1:
Carefully cut & remove 1/8 of the adhesive layers; you can find this 
layer at the bottom side of the membrane switch.

Step 2:
Pass the flex cable through the tail exit slot & position it on the back 
support recess. You may find the tail exit slot by turning the switch over. 
Adhere your switch to the unit’s surface with the exposed adhesive.

Step 3:
Position the membrane switch at 30° & peel the rest of the adhesive liner. Make 
sure to keep the setup exactly as in step 2.

Step 4:
Laminate the switch from the side, where you've removed the adhesive 
liner. For best results, it is recommended to use a soft roller by applying 
slight pressure while rolling it on the top surface of the switch.

Step 5:
Gradually, lower the angle of the membrane switch while rolling on its 
surface. Continue this step until the lamination is completed.

Important Note (Step 5)
1. At this point, don't bend the circuit or the dome. 
2. Make sure that you keep a minimal angle in front of your roller, 
which will help to complete the lamination by avoiding the air 
bubbles from forming in between the switch layers.

Step 6:
Lamination is over and can bend the circuit carefully without damaging the switch. 
However, you need to be careful while doing so. Make sure the metal domes aren't 
inverted or else it will no longer be functional.
If it is in place, don’t lift or reposition the membrane switch. By doing that, you 
might invert the domes/buttons and render them nonfunctional.

Important Note (Step 6)
1. Avoid creasing the cable when positioning the flex tail to create the 
final electrical connection. 
2. This might change the resistance or in the worst-case scenario, 
break the electrical contact altogether.
