After 30 years of specializing in designing and manufacturing custom membrane switches, SSI Electronics is now offering several standard membrane switches. These switches will be stocked and ready to ship to you without any of the design and tooling expenses often associated with membrane switches. You can use these switches individually or join them together to create the number of keys required for your small volume applications.

Standard Overlay Artwork Options

NOTE: Size of overlay is .020” larger on all 4 sides than switch (see above)


Overlay Options

  • Permanent: SSI stocks production quality overlays in the artwork formats found on the previous page of this brochure. These overlays have a matte texture and are printed with a black background and light gray text.
  • Non-Permanent: SSI can create a customized overlay by modifying the standard artwork and digitally printing the overlay. This option should not be considered a permanent option as the inks will not withstand long-term use. A design charge will apply for this option.
  • Customer Created: SSI can supply you with the standard graphic artwork in Corel Draw format. You can then edit the file and use an inkjet printer to create a non-permanent overlay.

Creating Unique Configurations

The switches have been designed so that two or more switches can be joined together and still maintain the center to center spacing(.750”) from keypad to keypad. This feature allows you to configure an abundance of keypad combinations.
