As always, excellent service, with very good products. Although there are many other companies, I do not switch to Air Spruce!

Looks good. Fits in the hole. Seems fine. Query logical difference between line and load --- dont think that the electrons care

Good out of the box. Per earlier review, pulled SAIB CE-13-22. It reports design mods to mitigate the reported failures on high-use SSCBs (cycled multiple times per flight) and there are no additional ADs at this time. Will monitor building from scratch so have a set of all-new CBs right now. Many thanks to prior reviewer Jay for that info in 2018.

I have used quite a few of these now, some in service for about 8 years. No issues at all. They work great. I have used 30 amp as masters, down to 3 amp for avionics. All have worked flawlessly.

Q&A

Q: Can you use these with a switch guard? I want to use two of these to run two fuel pumps and want to guard them whilst on so they cannot be bumped off. But - Can they still trip against the guard?

The arm is the same length as a toggle switch that would be used with at switch guard, so it "should" work fine. If the switch/breaker is positioned to be on when the guard is down, it would stay on until the guard is lifted and manually turned off. Remember each application is different and we cannot guarantee that it will work in all application or situations.

Q: Are these CB toggle switches FAA/PMA?

These toggle switches are commercial and have no FAA approval by themselves. They are commonly approved by the airframe approval if they were OEM on certificated aircraft. Please confirm in your parts manual or with you A&P to determine whether these can be used in your airplane.

Q: Can these breaker/switches be legally used to replace fuses in vintage certificated aircraft?

These toggle switches are commercial and have no FAA approval by themselves. They are commonly approved by the airframe approval if they were OEM on certificated aircraft. Please confirm in your parts manual AND with you A&P to determine whether these can be used in your airplane.
