Questions & Answers about Blue Sea Systems M-Series Battery Switch Selector:
2013-04-19R CLARK asked: Is knob or key removable in all positions?
+Expand Answers
2013-05-03HAROLD JOHNSON: No. It does not appear that it can be removed unless you pull it off the shaft with considerable force. It may not go back on easily if you do. No set screw.
2013-05-04DAVID BOYER: Never tried to remove the the knob.
Tried to pry it off with flat blade screw driver today.
With effort it comes off in the off position.
Tried other three positions. May come off with more force.
But I didn't want to take a chance on breaking it.
Sorry can't give you a better answer.
2013-05-06ALAN MACBRIDE: Yes, it is. I didn't realize it actually came off. That's how well it fits on. It turns in either direction smoothly and can be removed with a firm grip. The knob snaps on and off crisply.
2013-05-08DAN BAUGHMAN: Looking at the knob there is no screw or pin in the top or side of the knob, so I think you have to take it apart to remove the knob on the inside ???

2012-06-13A shopper asked: how do you hook it up?
+Expand Answers
2012-06-15HAROLD JOHNSON: I ordered the switch so as to be able to switch from battery 1 in my camper to battery 2, or turn both off, effectively turning off my 12 volt system. You can also turn both on at the same time. I no longer have the diagram for hooking it up, but as I remember it is a straitforward approach of hooking the cable from the alternator to the appropriate contact on the switch, then hooking the positive cables for each battery to the appropriate contact on the switch. Of course each battery must be grounded to the chassis. You will need 2 additional short cables for this.
2012-01-09BRUCE B asked: I have 2400w at 48v DC input from my solar array. Want to switch between my current "grid-tie" inverter system and a new install "off-grid" battery based system. Ideally it would have a min continuous rating of 50a and 48v DC. I see the M-Series Battery Switch Selector has a DC rating of 32v, so advise if you have any other product meeting my needs?
+Expand Answers
2012-01-31STEVEN RICHARDS: Bruce the 32v rating generally describes the insulating qualities of the switch. Meaning if you were to use this switch at 48vdc, it could technically "arc" and cause a short circuit. Have you considered a transfer switch that is rated for AC current (house current)? You would likely only use one of the "poles" of the switch, but it would work fine on DC current as long as it was rated for your 50 amps of current (which is pretty low for a transfer switch). Hope this helps, - Steve
