2004 Dolphin Water Heater Switches

The two water heater switches in my '04 Dolphin are getting a little intermittent and I'd like to replace them. I know the size and that they're three-pole illuminated switches, but not sure whether they mount to a PC board or connect with wire spade connectors. If the former, the spacing and size of the terminals will be critical, but otherwise not so much. Can anyone tell me which type these are? I'd go look for myself but my moho is miles away at present. Thanks!

Solved!

Ok, turned out I had to take DW to get medical tests today and the lab was just a couple miles from our storage yard. That meant I was able to go to the moho and see for myself. They are NOT wired to a circuit board, so a standard illuminated switch should do the trick.

NAPA #786115 works for my 2004 Dolphin water heater switches. Only $4.99 at my local NAPA. Did have to file down the opening ever so slightly and trim the clips on the switch that hold it in (due to our panel being thicker than the switch was designed for) but this took no more than a couple minutes.

These are low voltage DC switches, which is what you want if you want the lights on the switch to work. However, I believe prior to 2003 or 2004 the AC water heaters needed a higher voltage switch as they were controlling the electric heating element directly. Later models incorporated a relay and switched the electric water heater with 12VDC.
