Need a Split Rocker Alt Field Switch

[Raptortail]

Recently every time I shutdown my M20M and turn off the split rocker ALT Field switch, the Alt Field 5A circuit breaker pops.  I can push it back in, start the plane and everything works great until I shutdown again.  A&P thinks the split rocker switch has a fault but he was unable to find a replacement from his suppliers (not sure how hard he looked).  Lasar doesn't have one.  Does anyone know where I can source one?  The Part # is 880052-525.  Thanks for the help.

You could try Don Maxwell in Longview Texas . He may possibly have one ?

I have purchased used parts for my M20M here: https://baspartsales.com/

 

It's best to call them,

May not be that switch

Check the connections at the alternators 

It could be the very small diode

1) Recently… something has changed…

2) every time… that something should be easy to find, compared to intermittent things…

3) Do you turn off the field switch prior to shut down?

4) Aircraft Spruce is worth a check for the switch….

 

The order of the sentence made me ask… 

All of my electronic devices are cold before shutdown… including the field….

I need the same part for my 1986 252. Part of the #2 plastic broke. I've ordered through LASAR but they estimate 2-3 weeks. Not sure how good that estimate is. If anyone knows where the split alternator rocker switch can be found, please advise. Thanks
