that solve almost any technical need or challenge, complete with expert design and engineering from Hoffmann + Krippner. If you’d like to speak with one of our consultants to solicit input about your project or to inquire about our membrane switches, please send us a message here. Membrane switches can be manufactured with non-tactile switches, which activate with 4 – 8 oz of touch pressure. Non-tactile switches are less expensive and provide the longest switch life. Tactile switches have a snap-action feel and may also be incorporated into a membrane switch, enhancing tactile feedback, but with a greater cost and lower switch life. The membrane switch circuitry is most often screen printed using conductive inks, which are typically made of silver, carbon, and/or graphite.
However, membrane switches have not been readily adopted since, during that time, the huge personal computer market was dominated by mechanical keyboards. Mechanical keyboards were preferred due to their more tactile feedback. They were made up of polycarbonate plastic films printed with copper or silver infused ink creating the electronic circuit. These were composed of two conductive layers with one spacer in between. The products were inexpensive but threatened by problems such as degradation and cracking of the polycarbonate film and missing tactile feedback.
