Subject: Re: Re: Switch Schemes for Reliability From: Alec Myers (alec@alecmyers.com) Date: Sun Apr 21 - 6:06 PM I suspect the failure rate of a single correctly specified diode is many many orders of magnitude lower than a mechanical switch. And you can parallel two, three or four such diodes if you wish.

Trouble with adding elements to our systems is they too have failure modes, downstream effects, etc. Diodes can and do fail open and fail closed. So, we have to put them in the Fault Tree and Failure Modes and Effects work, estimate failure rates, and see if they help or hurt for forced landings and dark avionics suites. Have not done it yet, but might yet. Billski Read this topic online here: http://forums.matronics.com/viewtopic.php?p=513492#513492
