Switch contact disc mfr. for coded switches - forming contacts projecting radially outwards from disc

摘要

The switch contact disc for coded switches has a plate produced as a metal pressing with a series of radial projecting contact arms (4,5,6) spaced at intervals. Those contacts not required are removed. A carrier disc (12) is positioned over the plate and connections (17) are soldered to the remaining contact arms. Once the disc is secured the surplus metal of the plate is removed to leave a circular disc with projecting radial switch contact arms. ADVANTAGE - Simplifies manufacture of contact disc.
