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'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 X10 Appliance modules contain a latching relay. At about $10 a piece this might be your best choice. The last time I looked at one of these, what I found wasn't a latching relay in the usual sense. It's a solenoid which drives a rotating two-position switching thingie. There isn't a separate "set" and "reset" coil. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

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.

This type of relay would work depending on the coil voltage. However
I would guess that voltage is also 120 volt. What I am trying to do is have the ability to switch 4-5 different lights (150-1000 watt) from several locations within the same building without all the hassle of 2 and 3-way switches. My plan is to have a relay bank that these lights would source from (total wire run of 60-75 feet) then have small low voltage/current pushbutton switches activate the relays. 4-5 small pushbuttons could control any light in the building from that location. I have thought about X10 but have also read more bad than good about the wierd things they do or don't do. Randy 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.

Randy,
The relays that I described in my other post came out of a house that did exactly what you describe. The relays were made for just that purpose. Most of the light circuits were switched with these relays and low voltage wires were run to various places to control them. They had 2 push buttons for each relay. One for on and one for off. Thinking about it, that is better than using only one button. With one button you are never sure if you are turning the circuit on or off. Especially if the light happens to be remote from where you are. Each switch location had a 3 wire cable run to it. The 24 vac transformer was mounted where all the relays were mounted. Next to the breaker panel. I think there were around 40 relays that I got out of there. It was a big house. With this setup you can control a circuit from as many places as you want to without getting into complicated wiring. Not trying to sell you relays, just telling how it was done. 73 Gary K4FMX On Tue, 13 Apr 2004 22:47:38 -0500, randy wrote: This type of relay would work depending on the coil voltage.

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 ----------------------------------------------- |
