Remote solenoid switch

I want to add a remote solenoid switch for my wind generator and solar to reduce wire runs and keep all switches very accessable. The boating-specific ones are very overpriced, of course. I found lots of various solenoids on ebay, for a fraction of the price. What type do I want for this application? I want one that only draws power when switching, not to hold it open for extended periods of time.

Suggestions??

Thanks a lot

Why not use a manual switch?

A solenoid relay is inserted in the power wires, at the same place a “normal” manual make-break switch would be.
ADDITIONAL wiring is required from the relay to the control switch location; actually increasing the amount of wiring, but allowing flexibility in locating the control switch operator.
A LATCHING type relay only requires power to open or close the switch contacts.
Google: Latching relay 12VDC

Thanks Gord, will look at latching type

Cheif engineer- To place a manual switch on this circuit where it is easily accessed ( at all other switches ), The heavy wires from the wind gen would need to be about 25 feet longer. The pole for the wind gen drops straight into my battery locker, so it will be convenient to use a solenoid switch which can have thin wires do the switching remotely.
