This circuit allows an SPST momentary pushbutton to act as a push-on push-off switch, using a DPDT latching (bi-stable) relay. It was originally intended to allow a single pushbutton switch on the dash of a vintage car to provide a latched function. The relay only draws current when it is being ...

Latching Relay to Use a Momentary Button - Ok I know that you can make a latching relay with the diagram provided on this site. I have done it and it works great for my application. the only problem is that it takes a little while to set up, it doesn't look the nicest, and it is rather large. I was

A latching relay is a two-position electrically-actuated switch. It is controlled by two momentary-acting switches or sensors, one that 'sets' the relay, and the other 'resets' the relay. The latching relay maintains its position after the actuating switch has been released, so it performs a basic memory function.

The relay has latching contacts, this means once energised and power is removed the contacts stay in that state until the second coil is energised. Once you have the system wired as above, you may find the indicators are back to front, this is due to the state of the relay when you first switch ON.

Both circuits provide an inexpensive way of deriving a latching function from a momentary switch and, just like a mechanical latching switch, the quiescent (unlatched) power dissipation is zero .

A latching relay can used (when triggered by an impulse) as a power switch to operate a circuit. Our solid state (ssr) version of a single pole relay is toggled on/off by a 12 volt momentary pulse (positive or negative). A momentary contact activates it, and it can stay latched until it receives another 12v pulse.
