Anyone have experience with dual coil latching relays? I'm trying to
replace old (1950s) Guardian latch relays as used in 1950s style
jukeboxes with more modern two coil latching relays but have had trouble
with some relays going to an indeterminate state if the power to the
coil is below optimum.
What I actually need to do is a circuit that only allows the Latch/Reset
coils to trip when there is sufficient voltage and current available...
This somewhat plays into the discussion on DC relay latching voltage
thread and I'm wondering if the Zener diode across the windings or in
series with the windings might help my design.
As for the old original relays, the contacts are getting so pitted they
can't be saved and Guardian hasn't made this coil assy for decades. They
don't turn up on eBay either.
Two opposed solenoids and an arm on the spindle of a rotary switch.
