Toggle Switch with relay

[juan438]

I need to make a simple circuit with a relay and a momentary button, but it has to have the behavior of a toggle switch. I did a diagram, but I know it's wrong, because the circuit opens when I'm not pushing the momentary button.
What should I change/add to the circuit? Thanks

Hello,

Have a look at this:

This circuit comes from this page:

What is the value of the DC voltage from the diode bridge?

Another option is to use a CMOS flip-flop IC, such as a CD4013, to provide an alternate action from a push-button.
Also I have a circuit that uses two MOSFETs in a bistable configuration.

What is the value of the DC voltage from the diode bridge?

12 Volts, but actually that'll be an AC-DC transformer to make things more easy.
