Hi Frank,

great idea to use relays because their function is quite simple to understand – and they are still working in many applications around the car / house / machine area – thanks!

The history of the Lectron relay:

  • since 1966 a component of the “Ausbausystem 2” set: 300 Ω, 9V, without diode = #8054 / #8100502
  • since 1975 with “Funktionsmodelle” a second version for 5V, 70 Ω, (TTL driven) without diode, #8100506
  • undated: Mr.Birett had built a prototype with one diode for Physics teaching
  • undated: Mr.Gürth used his own version to store 1 bit (TTL introduction)
  • until the 199x years both versions were available, but with different relay types: 70 / 130 / 180 Ω
  • since 2001 (RWO) the actual version with diode: 5V, 70 Ω, as #2504

Best,

Günther
