you can use 2 (996/986 momentary) switches, 1 normally open to latch a 12v relay and 1 normally closed to unlatch the relay.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hey,
I want to replace the blanks beneath the ash tray or in the dash in my 996 with on/off type switches (like the rear defroster or PCM off) so i can use them for my helmet cooler power and cool suit power.
I can't use side window switches since they don't stay on full time and i don't know how to modify them.
I can't find these anywhere! any 996 or Boxter will work.
Thx,
V
As far as I know all the switches used to fill those type holes are momentary switches. They all use a relay of some sort to power their respective circuits.

what about the ones for power seats? or PSE or even the rear wiper? I don't think the momentary thing is on the switch but rather on the circuit of the device the switch is controlling...
They sell those at Suncoast Porsche.... $23-$35-ish each

you can use 2 (996/986 momentary) switches, 1 normally open to latch a 12v relay and 1 normally closed to unlatch the relay. Use the normally open contact of the relay to turn on/off your cooling suit. Here is the wiring diagram.

If you want to get fancy you can use the indicator light on the on switch... just wire the indicator parallel to your suit fan or relay coil.
