Thank you in advance for any help you might be able to give me on this. I have been racking my brain trying to figure this out.
Quick background: I am installing aftermarket heated seats in my car and attempting to use the stock switches.
The stock switch is momentary and has two position. Hi and Low.
The aftermarket switch is constant (alternating) and has three positions, Hi, Off, Low.
I believe that two SPST Latching Relay should be able to be wired in following the stock switch and allow for an effective replacement to the aftermarket switch.
However, this will only work as long as you remember to disengage the Low position prior to engaging the Hi position. (I think, as I don't believe that both can be on at the same time, for the sake of the Heated Seat Relay). The aftermarket switch controls a simple DPDT Relay NO. (I think?)
It seems that I should be able to wire in some sort of logic into this whereby.
Can anyone offer any help as to how to achieve this.
Also... I'm considering using Digital Latching Relays for this as they are inexpensive, Any thoughts on this?

- Hi and Low can be off
- Hi can be on but Low must be off
- Low can be on but Hi must be off
- Low and Hi can never be on at the same time.
