12vdc latching relay - one pulse on/off - wanted

[easytim]

I needed a 12vdc latching relay that will latch on with one pulse, then latch off with the same pulse.

My power source is 12vdc and I'm using a touch circuit with a relay rated at 1 amp for its output.

Does anyone know where I might find a prebuilt kit that latches using 12vdc as its power source?

Touch it, it stays on, touch it again it turns off.

What contact voltage and current rating do you require? Do you need a two coil latching relay or will a single coil version work, that is do you have two seperate pulse signals or just one? Also need to know the voltage (12v?) and current capacity of what ever is generating the pulse signal.

Remember you can use lower voltage relay coil and just add a series resistor and run it at a high voltage.

I have one seperate pulse

I am powering the signal with a N.O. contact at 12vdc

I have a small electronic touch switch that uses 12vdc with a small relay on the board, what I need to do is latch its output when it is touch switch is touched. I will be switching under 1 amp to power two small transformers (wall warts) that power some LED lights

Here's an off-the-shelf solution. About 17 bucks.

The Link does not work anymore

I don't think it's possible to get a "toggling" relay that only needs a single control pin and even if you can you have issues with knowing what state it's in.

All latching relays I've seen need two control lines.

Here's the file attached, since the link no longer works.

I know this is old but, I couldn't help it.

Here is a relay flip flop.

Awesome worked great attached it to dpdt relay to make a polarity changer to run a blind, Projector lifter and a 150" conceiled screen.
All in a days work
