I ordered it as a replacement for an identical one that failed with less than 15 hours on it. Well see how it goes, its survived 2 hours of operation so far.

Worked great for my 53 Bonanza alternator upgrade. Was a perfect fit in place of my existing Gen switch.

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.

Q: These are marked load & line. Do they not require a ground wire? Thanks!

The line side is receiving power and the load side goes to the unit.
