If I switch the input polarity, will that switch the output polarity, + vs - output?

If you switch the input polarity the unit will not function at all. It has a diode. The unit will not light up. It will not turn on. It will not work. DC polarity must be connected as shown on diagram. Can you tell me why you wanted to change there polarity?

I also agree with Joseph the output of the relay "Has NO Polarity". The relay provides 100% isolation from the input.

Yes it can. By reversing polarity you reverse the direction of the motor. A double pull double throw switch works fine at this function.

It is a simple input/output arrangement. Power source is the input, supply to whatever device you want to vary the speed of is the output. This will only work in one direction, unless you swap the output polarity to run it in the opposite direction. Doesn't matter whether the + or - is the control path.

It can be switched, however if I recall correctly, the instructons don't tell you how. If you're a handyman sort, you can figure it out though.

negative or positive voltage is simply a reference to ground. reverse your power connections (leads) and you now have negative voltage. it does not have a dual output for both positive and negative voltagesgood luck

I HAVE tested this and BOTH inputs are merged; there is no "switch" or preference to use one over the other.

Yes, if that is all you hook up, that is all it will switch. But be aware, it cannot do dual outputs, just switch between single outputs if that was even in your thoughts.

I think it may be able to use both outputs at the same time, but only from the same source, not from 2 different sources.Yet to verify it's capabilities...

It seems it could work, it is a double pull double throw, almost meaning it can never turn off just change polarity(flipping the current). The switch works well for switching between functions possibly Foreward reverse function. I doubt that it is a direct swap but of you know someone who could install it it should work with a bit of fabrication ie splicing it into a harness.

No. This swich will not change input or output If you dont change it manualy.

No, no polarity detector. You have to change the connection to measure charge or discharge currents.

It doesn't switch. you should use one or the other. my guess is that it will blend the two signals but halve the output to each. I use the RCA with a converter to 3.5mm because it sounds better but that is probably just my unit, not a universal truth. you could split the RCA and add an external switch if you must have multiple outputs.

There is no polarity on the switch. Connect the one to the POS+ from the battery and connect the other to the POS+ to the pump.

the common is for your input voltage you want to use for the output(no/nc). Your neutral or negative would go to the device you are controlling. The output(no/nc) would then go to the hot or positive of the device you are controlling.

Sounds like you want to switch the output among various speakers with a mechanical device? The answer would be yes.

My switch has one input that can be connected to either the A or the B output; the two outputs cannot be switched "on" simultaneously.

Two inputs an one output. The reviewer who stated the opposite is clearly mistaken. The inputs are on either side and the output is in the middle.
