Master Switch RV12

[Gerald Clabots]

The light on my master switch of my legacy 12 has come unglued and fallen into the switch body.
Has anybody had this problem and if so would you have the otto switch part number to replace it.
Thanks
Gerry

To me it looks like an Otto K2ABHPCABA but double check me. I have attached the K2 data sheet for reference. Here is a link to Mouser...

While you are at it replace the trim switch with the long paddle version. It is *much* easier to use.

Again, please double check my part numbers!

Someone gave me these part numbers. I have not verified them.

K2ABNPCCFA Master Sw DPDT
K2ABHPCABA Avionics, Nav/Strobc. A/P Sw's (spare)
K2ABMAAAAA Trim Sw
K2ABNPCCFA Landing Light Sw
KIABBPCADA Ign A, Ign B (opt Fuel Pump)

Hmmm... the schematic shows the master switch is a DPST, not a DPDT.



Here is how the part numbers break down...



The first part number (mine) is a DPST like the schematic and only has an LED indicator at one end (again, like the schematic and like what I see in my cockpit).
The second part number (Mich48041) is a DPDT with LED indicators at both ends. I don't see how this can be right.
I suppose it could be a DPDT with a single LED at one end but that's not what the schematic shows. Pull yours out and see if it a DPST or DPDT, and let us know!

This is the correct Otto part number for the master switch.
