ACS vs. Bendix Ignition Switch

[231MJ]

Has anyone used an ACS ignition switch to replace the Bendix switch?  The price difference is significant (ACS = $140 and Bendix = $460 at Spruce).  

 

Side note:  I did not make Oshkosh this year - hope everyone had a great time.  The new avionics are really exciting.

Third option?

When I installed my EIS system I also put in their STC switch panel.  To me the key is not adding security and I prefer the simpler operation of just switches. Electroair told me you can install with 2 mags. More than ACS at $269 but more reliable in my opinion)

According to ACS, their switch is not approved for the Mooney.

Short answer: Yes.

Longer answer: I own an M20C.  In the early 1960's, the M20C used a switch similar to the ACS without the push-to-start position.  Instead, those early models had a starter interrupt switch that allowed a user to disconnect the starter circuit to hand-prop the airplane and still use the shower of sparks.  I am an A&P/IA and ran the idea by my FSDO that, as a minor alteration, I was returning my airplane to an earlier configuration in order to use this switch.  The switch has been approved as a PMA replacement, albeit for a different airplane type.  My FSDO agreed, I wrote it up on a 337 in order to document the process and make it an official part of the airplane records, I installed a starter disconnect switch as described above, and am now using the ACS switch (which I am very happy with, by the way.)

For your M20K- no way.  

Your Bendix switch probably just needs some cleaning and maybe a new switch plate, all readily available from Bendix.  A local locksmith can probably do the work.

Thanks, Andy.  I have searched the internet for the Bendix repair parts and just can't find a vendor.  Do you know someone that sells the Bendix switch repair parts?

 

Thanks

Go to the Continental website and look for manual X43002-1 it covers ignition switches. Parts should available through most suppliers.

I found the repair kit on the Aviall site.  Thanks for pointing me in the right direction.
