7 Questions you should ask when designing a Membrane Switch

7 Questions you should ask when designing a Membrane Switch

1.      Overlay or Membrane? Do you need a Membrane Switch that contains circuitry or just a Graphic Overlay?

 

2.      What size does the switch need to be? What are the dimensions and total thickness available for your Membrane Switch? To save space the circuit can be designed in a matrix layout resulting in fewer leads with a greater number of connections.

 

3.      Is a back plate or bezel involved? On the product the Membrane Switch is applied is there a back plate or bezel? If there is it can make the Switch easier to install on your finished product.

 

4.      Where will the Membrane Switch be used? Will the product be used outdoors? In harsh environmental conditions? Depending on where the Membrane Switch will be used different additives and materials can be used to ensure the Switch is adapted to work efficiently in its environment. From UV resistant, chemical resistant and anti-microbial materials and IP ratings of IP65, IP67 and IP68 means that every Membrane Switch can be tailor made to its environment.

5.      Are there specific ergonomic concerns with the application? Will the Membrane Switch require embossing so the keys can be easily located? At Fascia Graphics® we do rim, pillow, braille, dome or combination embossing to achieve your specific ergonomic needs.

 

6.      Is lighting required? Does the Switch require LED’s to provide visual indicators to the user of actuation? 

 

7.      Do you need tactile feedback? Is direct tactile feedback required to confirm the Switch was activated? At Fascia Graphics® our Membrane Switches can with either non-tactile, metal dome tactile or polydome tactile keys.
