There are "tricks" to cleaning ordinary relay contacts, but I am assuming that you mean the stepper relays here? Stepper relays are usually exceedingly reliable right to the point where the contacting metal is worn away. There is a caveat though - the voltage needs to be high (eg 48V) and the current preferrably in the multi-mA plus region. Steppers don't have that awful problem of having enough contact pressure at the de-energised position [which pressure then affects the field required for the enrgised state]. Wiping too of course. Unless you mean you had problems with the actuator?

I turned it into a clock. The displays were OK, I prefer nixies. Having LEDs, with the ability to control the brightness of individual digits would be a big improvement. There rearmost digits will be dimmer because they have to transmit thru more obstacles; making them progressively brighter should solve that issue. Also, the displays shown on the website were manufactured with much better materials and precision than what I had from ~1960. I eventually abandoned this clock because the relays were intermittent and would not respond to cleaning attempts. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
