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 (one for the high and one for the low) 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.
It seems that I should be able to wire in some sort of logic into this whereby.
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.
Can anyone offer any help as to how to achieve this.
Thanks again for any help you can provide
