COLE-HERSEE M-532 Switch Wiring Details

Where do I attach the wires [for navigation lamps] to a Cole-Hersee M-532 switch which has four screw connectors. Thanks--FISHNFF

The usual wiring for the COLE-HERSEE M-532 switch is shown in
If you send the switch to me I will use an ohmmeter to identify the terminals for you, but absent having the switch in my hand, I don't know of any way to identify the designation of the terminals on the switch. I have not seen any details from COLE-HERSEE about that switch.

Thanks. I have an ohm meter. I just wanted to see if anyone had the inforomation, I thought Cole-Hersee would supply the diagram somewhere. I remember wiring my 13 and 17 with a switch that had three positions. [OFF, ON-1 ON-1 and ON-2]. FISHNFF

If you can deduce the terminal layout of the COLE-HERSEE M-532 switch, please give us the details. The information will be useful for others.

I followed the link I give in the article I wrote (see above) and landed on the COLE-HERSEE catalogue page for the M-532 switch. On the catalogue page is says that the switch is a three circuit switch. From the nomenclature used on the catalogue page I infer the following:
There is a terminal marked B that is for connection to the battery.
There is a terminal marked R that will be connected to B in the two ON positions of the switch.
There is a terminal marked A that will be connected to B only in the first of the ON positions.
There is a terminal marked H that will be connected to B only is the second of the ON position.
I can summarize the switch as follows:
OFF: No connection between B and others
ON-1: B to R, B to A
ON-2 B to R, B to H
This is just my inference from reading the literature in the link that I gave you. If you discover otherwise, let me know.

Assuming that my inference above is correct, you would wire the lamps to the M-532 as follows:
The battery positive wires to B;
If using combined sidelights and an all-round light
The sidelight lamp wires to H;
The all-round lamp wires to R;
If using separate sidelights, two-bulb lamp masthead fore/aft light, and sternlight
The sidelight lamps and the sternlight lamp all wire to H;
The masthead forward lamp will wire to R;
The masthead aft lamp will wire to A.

OK. Thanks Jim. Now for the simpleton in me. Can anyone out there tell me what color wire goes to which post on a Classic outrage with separate bow lights, running lights, and anchor lights? I may try to add in a stern light to be legal. --FISHNFF

I am not sure what you mean by "running lights." When underway, an 18-foot power-driven vessel shows one of two possible combinations:
--sidelights, masthead light, stern light, or
--combined sidelights, white all-round light.
At anchor you should show only a white all-round light.
In the article I wrote (which is linked above) in the REFERENCE section regarding Boston Whaler navigation lamp wiring, I show the typical wire insulation colors that are used. There is no way for any reader to know on your boat precisely what wire insulation color was used for each lamp. To depend on the color of the wire insulation to identify function is not a good practice on a boat; often the wire insulation color is not a reliable indicator of the function of a wire.
Bow lights are not navigation lights. If you have some lights at the bow you should wire them to a separate switch, not the navigation light switch.

A much better and very simple method to identify the function of each wire in the navigation lamp circuits than just relying on the wire insulation color is as follows:
Locate the wire that connects to the power source for the circuit, usually a wire with red insulation which is from the secondary power distribution panel closest to the switch. Verify this with a voltmeter. Mark this wire B.
Locate the various wires which connect to the several lamps of the navigation lighting system.
Temporarily attach or hold together the power wire to each of the navigation lamp wires individually. Note which lamp is illuminated when its wire is connected to the power. Be prepared to mark or identify each conductor. A good method is to use a permanent ink marker--a Sharpie--and some white paper tape--Artist's Tape. Use scissors to cut the tape neatly; do not tear the tape by hand as this leaves a ragged and very unattractive edge for the label.
If using separate sidelights, two-bulb lamp masthead light with fore and aft sectors, and sternlight
Find the wire that illuminates the sidelights, mark that wire with an H.
Find the wire that illuminates the sternlight, mark that wire with an H.
Find the wire that illuminates the forward lamp of the masthead light fixture, mark that wire with an R.
Find the wire that illuminates the aft lamp of the masthead light fixture, mark that wire with an A.
If using combined sidelights and an all-round light
Find the wire that illuminates the sidelights, mark that wire H;
Find the wire that illuminates the all-round lamp; mark that wire R;
For all cases
Connect the wires to the COLE-HERSEE M-532 switch as follows:
Connect the wire(s) marked H to the terminal marked H.
Connect the wire marked A to the terminal marked A.
Connect the wire marked R to the terminal marked R.
Connect the wire marked B to the terminal marked B.

Thank you for the clarification. That helped greatly.
In regard to [the navigation rules for navigation lighting some secondary sources were given here. I prefer to cite primary sources. For authoritative on-line navigation rules see the USCG NAV CENTER--jimh].
I also went into a local [unclear, perhaps West Marine] store and asked the store manager and two different associates [for their interpretation of the Navigation Rules--again please see the primary source linked above--jimh].

I am pleased to hear that the additional description of the method for identifying wiring circuit for navigation lamps was useful.
I deleted your links to secondary sources of the Navigation Rules because the primary source is also on-line and should be used in preference to others.
I do not find that sales associates at marine stores are necessarily expert in the navigation rules, and I don't rely on them for advice about the navigation rules. I use the navigation rules themselves as the best source of information about the navigation rules.

[Changed topic to offer interpretations of RULE 23, navigation lights for power driven vessels when underway. Discussion of the navigation rules for lights for power driven vessels when underway is a frequently asked question. Please see the FAQ on this topic. Thank you--jimh]

Based on your comment that the additional details of the COLE-HERSEE switch and the method for discovering the identity of the navigation lamp wiring insulation color were useful, I have added that information to the REFERENCE article on this topic.
