Bob,
You won't be needing all those redundant power switches for your next ISS-attached satellite... they'll turn the power off for you at random intervals! (GRIN).

"Early Sunday morning the International Space Station experienced a power outage. By Monday morning all systems were back in operation. No systems were permanently affected and there was no impact to crew safety or station science.
A communications system that was temporarily down was restored shortly afterwards. One gyroscope that helps control the station's orientation went offline for awhile but eventually came back up. Several heaters used for thermal balance of external station components were affected but have since resumed normal operations."
Comms down... Gryos offline... Thermal problems with external systems ... not a crew safety issue.
2W transmitter outside in a box... better put four safety-rated power switches on that puppy!
LOL! Go spin Doctors, go!
