DPDT Golf Cart Switch

[TomG2]

My girlfriend keeps ruining the charging cable on her golf cart by pulling on the cord instead of the plug. How would a double pole, double throw switch work if it was inserted into the cable between the charger and the plug? She leaves the charger on the golf cart all the time. It is an older cart that requires the cable to be plugged/unplugged between charges.

Not sure what is confusing people. As stated in the OP, she leaves her charger on the cart. I want to disconnect it from, and connect it to, the batteries without her having to pull the charging cable from its port. It has the old "V" shaped connector and she damages the cable by pulling on it rather than the cable end. Yes, it would be great if she would grab the plastic shroud instead of the cable, but it will be even easier if I rig a switch to connect/disconnect the charging cables.

What people may not understand is that her cart/charger combination requires that the charger be separated and then reconnected to the batteries before it will attempt to recharge them the next time.

Confusion here.
On board charger?

I see where I might have misled you. It is the cable between the charger and the batteries that I am concerned with.

Might be something here you can use...

You only need a single throw switch. If it's a two conductor cable that attaches to the two battery terminals, you really only need a single pole switch.

Edit: Unless it's unplugging the battery from the charger and plugging it into the golf cart...though I really don't see any reason why it's electrically necessary to unplug the golf cart during charging (i.e. it's only necessary because the cables physically require it, not because the charger output would harm the golf cart as its parked).

I see no reason why it would not work effectively provided the switch is adequately rated. A battery disconnect switch such as is used for boats etc. would be a good choice (if perhaps overkill). The switch will be happiest if the charger is turned off before throwing the switch so that it's not trying to open when there's significant current flowing.

If you wanted to be clever, you could also wire up a relay/solenoid of the appropriate rating to the power feed of the charger so that it switches automagically as needed.
