Manufacturing processes are carried out in-house by our team of experienced staff, in clean, controlled environments. This enables us to control every aspect of production, ensuring that the finished product is of the highest quality and delivered on time.

How does a membrane switch work?

Membrane switches are normally open, momentary contact devices. They are made up of a minimum of three separate layers - a flexible upper contact, a stationary lower contact, and a spacer to hold the contacts apart until pressed.

A basic membrane switch

The contacts are screen printed onto a clear, thin-film substrate such as PET, using a conductive silver or graphite ink. A flat tail made from the same piece of substrate provides connections to the switch.

The spacer is produced from a sheet of double-sided industrial adhesive, with holes punched at the switch positions and vent channels linking them. The adhesive on each side of the spacer then holds all components together in a laminate.

A membrane switch panel can be just a single membrane switch, or an array of multiple individual membrane switches.

Membrane switches are known by many different names including flat switch, flex switch, membrane push button, membrane touch switch or sealed switch.

Celebrating 50 years - 1960 to 2018

During 2018 we are celebrating 50 years since the founding of our parent company, Permasign Limited. Originally manufacturing laminated bus stop signs for the local council, we have come a long way and developed a lot of products during that time.

We'd like to thank all of the wonderful companies that we've had the pleasure to work with in the last five decades, we're looking forward to the next half century and beyond.
