Question

Is knob or key removable in all positions?

Asked on 04/19/2013 by R Clark

Top Answer

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 ??? DAN

Answer

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.

Answer

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.

Answered on 05/04/2013 by DAVID BOYER

Answer

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.

Answer

That depends on whether you want to route power to your electrical system from battery "A", or battery "B", or both at once. If you simply want to double the capacity of your battery bank, then "no, you don't need a switch."

Answered on 11/29/2013 by ALAN MACBRIDE

Answer

Switch is good idea. You can change from one battery, when it gets low, to the second easily. Without a switch you must change the cables from the first battery to the second battery when you need it. The only other alternative is to hook up the batteries in a parallel mode (+ to +) and (- to -) and the batteries will go down simultaneously but should last twice as long.

Question

What would cause switch to not turn off DC voltage from batterys?

Asked on 08/16/2013 by Undisclosed

Top Answer

Maybe its wired up wrong or has a short in it ???

Answer

I would guess that it is wired wrong on the terminals. I noticed that the terminals do not really line up with the markings on the face. I had to verify each terminal with a volt meter to make sure I was connecting the leads correctly. Should be an easy fix once you figure out the layout in the back. Hope this helps - Steve

Answer

I really don't Know. I would suggest that you re-check the way you have it hooked up. The diagram is a little hard to read. As I recall it was a little difficult to match the markings on the switch with the diagram.

Top Answer

The dimensions are 2 3/4&quot; wide, by 2 3/4&quot; height and 3&quot; long (from the back to the tip of the knob). You have 3 mounting options Surface, Front panel or Rear panel, thank you.

Question

how do you hook it up?

Asked on 06/13/2012 by Undisclosed

Top Answer

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.

Question

I have 2400w at 48v DC input from my solar array. Want to switch between my current &quot;grid-tie&quot; inverter system and a new install &quot;off-grid&quot; 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?

Asked on 01/09/2012 by Bruce B

Top Answer

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 &quot;arc&quot; 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 &quot;poles&quot; 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
