Mail addressed to hydra.unm.edu!ee5391aa bounced badly, so pardon the
post:
%>I have an application where I need to activate a SPDT set of contacts such
%>that the toggle action does not release after the coil voltage is removed.
%If you want to do this on the cheap, try to get hold of an old VW headlight
%relay. These things were used to toggle the high-low headlight beam from an
%SPST switch. The drawback is that the contacts are SPST, too. You might have
%to use a second relay (your choice of contact types).
Or get the one out of a junkyard Volvo - my '71 145 had a Bosch SPDT relay -
I had to replace it once, and went to a junkyard. Every 140-series one I saw
had it - and a SPDT is just what you say you need. Watch the coil current,
some of them will draw a amp or so.
