Contactor or Solenoid

I am looking to add a 5 button wireless Lewmar remote to operate my windlass and bow thruster. According to Lewmar remote kits can only be added to devices that use solenoids. My Lewmar V4/V5 windlass uses a contactor.

I am wondering if Lewmar uses the term "solenoid" in the general sense to describe an electromechanical device. I believe a contactor is also an electromechanical device. If so, I believe I can add a remote device to my windlass.

Please Help!

Wherever you go... there you are!

Don't worry about the semantics.

A relay is an electrically operated actuator switch*.

A CONTACTOR is just a heavy-duty RELAY that can handle the high power required to drive an electric motor.

* There are two basic types of RELAY actuator:
- the direct-acting SOLENOID, in which a moving core or plunger is drawn into a coil when current flows;- and the simple RELAY, in which a hinged plate is pulled against the end of the coil.

Contactors, relays and solenoids are used approximately synonymously.

I guess it is a matter of personal preference but I would use a separate switch assembly for the windlass and bow thruster. Lewmar sells a rocker switch that will control your windlass remotely. Your Lewmar "contactor" has three wires that you need to hook up to the remote switch: pos, neg and neutral.

My anchor winch & single (can't afford more) cockpit winch both have switched low current "arm" circuits to enable/disable the relays controlled by the main operating switches.

This is in addition to high current DC breakers in the main battery feeds.

The arm circuits provide a degree of safety & security when the winches aren't required.

If in doubt RTFM
