Default BEP Battery Switch Failures

Just bought an 06 2360 Sailfish with 150s. (Thanks to all who counseled me with my shopping!)

Love the boat but on my first weekend of use one of the two BEP A/B battery switches failed. The switch was the original factory installed one. I bring this up because I used this same BEP switch on a past single engine boat and had it fail three times before going to a perko.

I'm trying to decide if I should replace with the same (which seems insane) or go through the trouble of switching both switches out with a different brand / model.

Has anyone else had a problem with BEP?

Did it "fall apart"? We had those issues a few years ago at Proline...

I'd go with Blue Seas.

Yes... All four times the switch fell apart. With the old boat BEP told me it was failing because the switch was not made to hold any cable weight hanging down. The third one they sent me was slightly different and was supposed to be more appropriate for stand alone mounting (as opposed to in a cluster with all cables supported) It still failed just the same though.

Will the blue sea fit in the small mounting hole I have? i'm thinking not.

The spring causes the injection mold to crack, when they get hot (not from load, from natural heat). Always keep a spare aboard, they are prone to break.

Heck, I was just getting ready to spend $260 on a cluster.

My boat came with 7 from the manufacturer. They have all failed twice. It has nothing to do with the attached wiring. The spring aparently fatigued the plastic and the mold failed. I wish I had room for a different brand. I oppose using switches I'm sure are going to fail. I keep several spares on the boat.

Did you guys have the "mini" switches? The footprint is small, which a lot of builders liked...

If the Proline plant was still open, I could show you a pile of broken switches...

Question: When one switch in the cluster fails, don't you have to take the entire cluster apart to get the one that failed out?

Yes. I had to swap out a motorized switch on a triple Verado 35 Express when they first came out with the motorized switches...3 switches, 3 VSRs, 3 parallels...on my stomach, at the Vinoy in St. Pete, in July...that was fun!

Well I guess the BEPs have to go then. I have plenty of room inside the console for bigger switches and I darn well know a medium duty perko switch will last much longer. There's too much that can go wrong offshore to be relying on a switch that you know is eventually going to fail.

My cluster has 7 switches, 2 VSRs, various circuit breakers etc. The whole thing have to come off a bulkhead to replace a single switch. Mine is tightly fit under some steps or I would have changed brands by now.

The plastic on some circuit breaker panels has disintegrated as well but I replaced them with custom made panels.

Please explain the failures further, was it in the back of the switch with the wires, front knob, were these switches thru hole mounted or surface mounted ...what exactly failed?

The seam, where they would overlay and meet the square box part, always fails, if left in on (as I do), no issue with performance, but they fail from heat and design.

To BMW
All the switches I'm speaking of are flush mounted. The first two on my old boat had corner mounting holes but no capture nut points in the back. (I just used washers that pressed against the back corners. The third one BEP sent me was almost the same but had capture nut holes in the back and I used those. BEP stated that this design would hold up better.
The housing or body of the switch and the turning handle remain in place when it fails. When switching you begin to notice it's not very tight and doesn't click into each position solidly. (you hope you begin to notice!) At that point power will be intermitent if at all. The back plate of the switch with all the studs will just fall off with all the wires still connected. The weakness appears to be the plastic points that join this plate to the switch body.
I'll try to post a few pictures when I do the repair.

Only part (so far) that I've had to fail were two of the handles, and I think they were forcefully turned creating weakness and later breaking off. I was able to turn the shaft with pliers until replacements could be installed. This did happen two different times. I've never had one to break on the inside tho...that could be bad!!!!

I have seen "switch" failures, as well as the failure Wooden describes where the mechanism that the studs are attached to actually separates from the switch itself...that would suck if the switch were somehow mounted directly above the ground stud on a batt...and it fell on that stud! Oh boy, onboard welding!!!

I had Perko and Blue seas and never had any failures whatsover. A battery switch is one of those things that I never even considered replacing since I never had one break. Ive had 20 yr old switches on my old boats and no issues. I wouldnt use BEP if thats a common failure.

I've seen a couple of failures but this 716 on my Whaler has 5 years and 2200 hours on it and never missed a beat.
