541 Series

541 Series comprises reed pushbuttons, as advertised in June 1977 in Electronic Design magazine. The switches are shown advertised with standard truncated keycaps, but they are not known at present to have been used in any keyboards. These switches are rated for 50 V DC at 20 mA maximum, which indicates that they are intended for use in electronic circuitry only. Contact resistance is given as 0.5 Ω maximum when new, and 1.25 Ω at end of life. Rated lifetime is not mentioned.
