Trimbulk Memtron Technologies' latest series of membrane switches takes up less space. Reducing the number of switch layers while integrating more functions, using advanced soldering, circuitry, and LED spacing, result in data entry panels having a stack-up thickness as low as 0.04 inch. This is about half that of conventional larger area membrane switches, according to the company. Maximum operating voltage is 30V dc and maximum current is 30 mA. Lifetime is one to five million cycles, depending on tactile element selected. Such low profile switches are well suited for small, complex, hand-held instruments.
