Help Finding Latching Relay
I'm looking for a source of new latching relays.
Coil needs to be 12 to 24 volt and contacts of 10 amps at 120 volts AC. The catch is I don't want any dual coil type relays. I have an application in which I want a contact closure on the coil to turn the relay on and another closure will turn it off again. I would even be receptive to a solid-state module that would give me the pulse on / pluse off action that I could use to control a relay. Randy BC |

I have a bunch of 15 or 20 amp latching relays that were used in house
wiring. But they do have 2 coils. One to latch and one to unlatch. 24 vac coils. 73 Gary K4FMX On Mon, 12 Apr 2004 22:32:04 -0500, randy wrote: I'm looking for a source of new latching relays.

Randy BC All latching relays have a dual coil setup, with a mechanical latching arrangement on the armature. If you want just one coil, you need a simple flip/flop driving a transistor whose collector load is the relay coil. Lots of example circuits in the Handbook of Electronic Circuits Vols 1-7.

A lot of automobile headlight relays switch states with a pulse to a single coil. They're 12V, too. - ----------------------------------------------- Jim Adney Madison, WI 53711 USA ----------------------------------------------- |
