I had some heated seats retrofitted to my car. I have wired them so that a 12 V ignition signal activates a relay and powers a bus bar which then powers the seats.
The switches are round ON-OFF-ON switches. So if someone leaves the passenger switch ON and I just get in and don't notice, the seat will always be on.
My query is: can a relay, latching relay or something else be put inline somewhere that will, in effect, reset the power to each seat?
This means that if you left it on and cycled the ignition, you would then need to go to OFF, then back to ON to get the seat to work on the rocker switch. This is essentially overriding the switches' physical state.
