Blue Sea Systems 9001E e-Series Compact Battery Switch 4 Position Selector Switch, 32V DC, 325A, Red

Excellent product. After having long thought that Perko was the gold standard in marine accessories, I took a chance and changed brands when the sea air had finally given my battery switch all it could take. I am very happy with my choice. Functionally, they are all pretty much the same. The difference for me was, since the unit is open on all 4 sides and not just the bottom, routing your wires is very easy. The switch is also physically easier to turn than the one I took out ( which is good on those bad arthritis pain days).

This is the perfect switch I need to add the second battery to my pontoon boat. Strong lugs and easy to mount securely. Slots make it easy to route the cables cleanly, too.

Solidly built, easy to install/use, and should last a long time. The switch functionality is very good and handles a lot of current. My only complaint is the lack of a back which leaves the connections exposed. I used a piece of rubber to put on the back so the connections weren't exposed to the metal boat frame I mounted it to. I highly recommend this brand-name unit over other cheaper products. This is a clear scenario where you don't want to get bit by the "you get what you pay for" truth.

Have used this brand for several years with no issues. Installed thi on a boat i am rewiring

Functions well

The switch was a breeze to install, feels very solid, and I expect it to last a long time. I'm sure this is a little over-kill for my single marine battery, but I'm willing to pay an extra twenty bucks for peace of mind. This switch has a very high threshold for the load of amps that occur upon starting the engine, and it's size and weight imply that I won't be replacing it any time soon. The ability to flush-mount it worked great and keeps it looking professional. Regarding my specific setup: I have a standard marine battery running to a 120hp Yamaha outboard. For the last couple seasons I have had an issue with the battery dying if I didn't use the boat for several weeks. Physically disconnecting the battery terminals after using the boat solved the problem, but it wasn't the most user-friendly solution for the rest of the family. The issue suggests a larger trickle from the battery than there should be, but it's not worth my time or money to figure out what device is pulling current even when the key is off. So the solution was to get a simple switch that does the same thing as physically disconnecting from the terminals. It's worked great so far; no battery drain after leaving the boat for a month. Originally I intended to mount it below the dashboard, but I ended up taking more simple route and mounted it closer to the battery in one of the compartments under a back seat. I used a 3 5/8" hole saw to cut through the plastic wall of the seat, about halfway up from the floor. Then I pushed the switch into the hole, marked the four locations of the bolts, drilled four small holes, and mounted the switch with four nuts and bolts. NOTE, I needed the following extra materials to install the switch: 1. 3 5/8" hole saw (not needed unless flush-mounting, and you could use a different tool too) 2. Four bolts and nuts (at least 3.5" in length, I forget the diameter) 3. Wire and crimp-connectors to extend the wire from the battery to where I mounted the switch, remember that you only need to extend the positive (+) cable to the switch)

Go for this switch you won't be disappointed! It looks great, is very well built and functions properly. There are 2 caveats: 1) This switch is very large, the face size is 3 5/8" - so if you are planning on the "flush mount" or "rear mount" option, you will need a smooth-cut 3 5/8 hole, which is a rare hole saw size, so you'll probably want to order one of those at the same time. 2) It doesn't come with mounting hardware. I used 1/4" marine grade nuts/bolts/washers. I did the flush mount option and I used 1 1/2" bolts which were a touch on the small side for flush-mounting. I would recommend 1/4 x 1 1/2" bolts for front mounting and 1/4 x 2" for flush-mounting. Upon installation and first use I was extremely happy. Jammed the stereo with sub-woofers for over 2 hours on the lake in position "2". Attempted to start the boat in position "2" - click-click. Switched to "1" and she popped right off! Exactly as intended! I have yet to be 100% sure that it recharged both batteries in 1+2 mode, but it really must.

Easy install, very durable and well made. Makes your battery life worries not exist

Missing nut :(

Quality Item, but expensive for what it is. Bolts require 10mm Cable Lugs for attachment.

Prodotto di qualità

Quality you can feel. Note: Not the same mounting holes pattern that the older version.

Provato con corrente di 100A e non diventa neanche tiepido. E' tutta un'altra cosa dagli stacca batteria cinesi. Anche le dimensioni sono monto abbondanti. Ottimo
