I always use one of these to make an avionics master switch.

The picture of this breaker is correct however the part I received was reversed with the LOAD printed on the top terminal and LINE printed on the bottom.

Ed M Verified Purchase

TE P&B CIRCUIT BREAKER W31-X2M1G-10

This part was labeled incorrectly. All other circuit breakers have the LINE terminal on the top and LOAD terminal on the bottom.

Direct replacement to existing breaker. Easy to install and works perfectly.

Second Tyco circuit breaker Ive purchased. It works, service was prompt.

It works

Received ina timely fashion, looks good but not yet installed.

I needed a couple of circuit breakers switches and the web site at Aircraft Spruce delivered... I promptly received my order. everything was packed well.

Arrived in short time. Excellant service.

Only place I could find this item. Thanks for stocking them!

These Tyco switch breakers are a great replacement for failing switches. Pricing far better than competition. Spruce is always fast and accurate.

part was good and your service was excelent

Perfect replacement for a Potter Brumfield that failed fit the buss and is holding the circuit.

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

Excelent product and quality, always pleased with you guys.

Works as expected.

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.

When looking at them face on, compared to the vintage Klixon switches they replaced, these switches are slightly narrower and taller. They barely fit as replacements in my aircraft. Check dimensions carefully.

Product delivered on time and in good condition.

Seems to work just fine.

Good switch I was looking for that brand name.

Good out of the box. Time will tell longevity.

I’ve used these switches in my last 2 homebuilt RV aircraft. I like them. Only problems I’ve had are After plane parked on ramp for an hour on a hot summer day, I could not turn on switches on due to heat from sun. Covered / shaded with my map for about 10 minutes to cool them down - started workin again. Just had toggle arm break off at base when I flipped switch on. (8yr old-360hrs) This is a first for me but I see a review where it happened to someone else...hmmm.

I have several of these installed First one to break off at the root of the toggle. Switching has worked fine. A little expensive For what they are. Switch was eight years old. Hope this incident was isolated.

Sad it is made in China. A country that does forced organ harvesting for political and religious prisoners

I replaced the failed switch, which is the same brand but made in Mexico, with this switch now made in China… I don’t have my hopes up for quality.

First part was defective where the toggle broke off on first use.

Robert L Verified Purchase

TE P&B CIRCUIT BREAKER W31-X2M1G-10

I would like to see a design that provides a better visual cue that its tripped. The disparity in pricing between the same switch in different amperages seems high.

Made in China. Feels like as well. Otherwise similar to the OEM breaker.

I have several of these installed that are 9 years old. The handles are breaking off systematically On the ones most frequently used. Obviously they have a cycle life. Ones currently used on every flight are failing one by one. Aircraft has 500 hours now.

In Brief. The FAA has issued SAIB (CE-13-22) which advises owners of airplanes with W31 series switch style circuit breakers made by Tyco or Potter Brumfield of an airworthiness concern. There have been known continued failures of these SSCBs on Cessna Aircraft and other and on homebuilt aircraft. They do nor advise using them beyond 600 hours in heavy usage. Spend a little more and get a better circuit breaker.

After the first one shattered I did not dare try to loosen the screws on this one.

Poor quality. Switch does not make a clean contact when toggled. I will not be installing it in the aircraft. Disappointing.

Third W31 replaced. In all cases, the lever broke off.

These fail. 3rd one now. 1st lost contact and caused Pamel out on approach 2nd one broke off 3rd fails after install and does not stay up. Unclear if they are fakes as markings and production location vary significantly.

brand new 2 amp switch did not work - requiring a second switch to be installed.

I have replaced the W31X2M1G15 installed on my Whelan Flasher circuit twice within the last 4 years. The last one lasted only one year! They short out and the circuit won't stay energized. Very dissatisfied!
