I need to replace the water heater panel switch because the LED is burned out, and I sometimes forget to turn it off. No part number on the switch. I think it is a Sigma switch (blue LED). Not having any luck with internet searches. Does anyone know where I can get a replacement? Thanks.
If it's the WH electric switch probably a SPST (single pole/single throw) blue illuminated rocker switch (energizes a relay). The size is pretty much standard across the industry but the bezel may be a different shape.
Since those switches trigger a relay, are they interchangeable? Would it be possible to switch the overhead light switch with the other switch? Its not like I need a lighted switch to tell me the lights are on. Just speculating because on mine, all of the switches are on the same panel. your's might be different.
