need help with a switch

SPST is a Single-pole/Single Throw switch,
a basic on off device. If it is lighted, it will have a third post or wire which you use to ground the bulb. The bulb will be on anytime there is power to the switch. Which means I don't think you can use this type of switch on the ground side of whatever load(device) is powered up from another source. In this case you would have to use the switch to power up your load. If the switch is not of sufficient load carrying capacity, then you use a hi-current relay, usually called a solenoid, and turn it on with your SPST switch.
If your load is a DC motor, like a winch, that needs to be reversed, then yes you have to use a DPDT, which a Double Pole/Double Throw switch. (basically two SPSTs in one housing with one toggle) But again, it has to be of sufficient current carrying capacity for the load.
Switch-style #2 is what you want.
They make this kind of HD switch specifically for this application, but I've never seen a lighted one.. But that doesn't mean that you can't wire a remote bulb to it. You can find this switch and the relays/solenoids at any place that sells trailers or a place that sells ATVs and Side-by-sides.

Incandescent bulbs are not particularly fussy about in which direction the current is going thru the filament. but I think LEDS are
Hope that helps
