I bought these Honeywell illuminated rocker switches

 

[img]cid:image002.jpg(at)01CF03E0.8591B470[/img]

 

 

which are DPST switches, ref. # AML34 FBA4AC01, and look like this from behind

 

[img]cid:image004.jpg(at)01CF03E0.8591B470[/img]

 

The 4 inclinated lugs are obviously the source and load for each pole, but I’m having trouble to find out how to connect the upper lugs, i.e, how does the illumination lamp circuit works.

I suppose I’m having a brain freeze here…

Since they didn’t come with any schematic drawing, and I couldn’t find it online, can somebody please tell me (or send a hand draw) how does the lamp circuit works?

 

Thanks

Carlos

   You'll find two AML documents there that

   will probably cover your questions.

Bob

Thank you for your quick answer.

 

I already had grabed those 2 documents over the internet, and in none of them I was able to conclude how does the lamp circuit works, and how shall I wire these critters to get them illuminated…

 

Could you draw a simple hand sketch?

Thanks Bill

 

But those are the same documents that Bob has pointed out, the first is only a drawing with physical dimensions of the switches, and from the other one I am not able to understand how the lamp circuit works..

Hi Carlos,

It would be helpful if you would provide any markings shown on the switch housing / packaging. 



At the bottom of the download document aml_30.pdf, on page 4, it shows connections for the internal light.  On many switches, the lamp circuit is independent of the switch circuit.  I am guessing that you have an isolated lamp circuit and that the two straight terminals are for the internal light.



Hope that this helps.  Have a great new year.

In that case, the switch light is not commanded by the switch itself, isn't

it?

So, if I want the lamp to illuminate when I turn On the switch, I'll have to

wire that externally. Am I correct?

YES and YES BUT

Oops again

I re-read your post & p 4 and see your switch AML34 FBA4AC01 is a:

AML 34 F > â€œRectangular 1 lamp circuitâ€

B              >  â€œBlackâ€

A              >  â€œNo lamp installedâ€

4               >  â€œ.187 x .020 (Solder of Quick-Connect) terminal

AC            >  â€œ2-Poleâ€

01             >  maintained ON and OFF



I find the second â€œAâ€ intriguing, as it hints that NO incandescent lamp was installed??  Honeywell MAY be using the same body on multiple switches and your switch MAY have lighting terminals, but no light installed.  Try a resistance measurement between the two straight terminals.  An incandescent light should give a relatively low resistance reading.

   According to the number you cited, the switches you have

   are black, rectangular devices with one lamp circuit, no

   lamp installed, with .187 fast-on terminals and two Form A

   contacts (two poles).

 [img]cid:.0[/img]

    



 I presume you have #73 or #85 lamps to install



 

 [img]cid:.1[/img]



   The schematic for these switches 



 [img]cid:.2[/img]



   Shows the two poles on terminals 11/12 and 21/22 with

   the lamp isolated on the other two terminals. The elsewhere

   in the literature I found this rear view of the termina

   arrangement



 [img]cid:.3[/img]



   If you look at the back of your switches, you'll probably

   find numbers molded into the housings.



   You probably only need one of the two poles to switch

   a load so you can use either the 11/12 or 21/22 path

   for this task. I presume that you're going to power all

   the lights from a dimmer so one of the two lamp terminals

   would be tied to ground . . . the other to your dimmer

   output. For side-by-side switches, you can daisy-chain

   jumpers across the row of switches to parallel all the

   lamps and take single conductors to ground and dimmer.



   . . . sorta like this.

Carlos;  

   

Referring to the document AML30.pdf and analyzing the part number you have provided shows that you bought the switch without a lamp installed indicated by the "A" in the centre of the part number. You did buy the appropriate lamp to install in this switch according to the voltage you require didn't you? If you wished it to come with a 12V lamp already installed the central “A” should have been a “C”  

   

AML34 ORDER GUIDE  

AML34 accepts one incandescent lamp which can be furnished installed or ordered separately.  

AML34 F B A 4 AC 01 has no lamp installed AML34 F B C 4 AC 01 has a 12V lamp installed. For 28 volt it would be an “E”

In AML 24, 34 and 26 (you probably have AML24)  any light circuits are 

independent of the switch circuits.  Looking at the spec sheet, they 

only show the diagram for the various switched poles.  You just hook up 

the lights directly to power and ground and possibly a dimmer.  I don't 

think I ever saw a diagram showing the light circuit.



The AML36 series has versions where the lamp circuit is integral to 

switch circuit.  I'm unfamiliar with those.



I used a number AML 24 and 34 switches, all with independent lamp 

circuits.  I had no desire to have the light do anything other than 

light up the switch label for night ops.



My switches were spec'd for incandescent lamps, however I replaced them 

with LED lamps with integral resistors sourced from one of the panel 

shops.  They are also dimmed with units from Perihelion.



If you need indicator lamps, the AML41 indicators are a nice complement.



The dimming is critical.  A bank of these switches and/or indicators 

will blind you at night.  At the same time, they are very nice at night 

when properly dimmed.  Re the indicators, I did not dim the 'warning' 

and 'fault' indicators, i.e. Oil Press, Low Voltage, Master Warn, Door 

Open, because they should be seen no matter how the dimmer is set.  I 

did dim the 'status' indicators, i.e. Buss Crossfeed and Boost Pump, 

because I didn't want to be blinded when those indicators are on for 

extended periods.



Here is a page showing some switch wiring - note that none of the switch 

terminals are connected, only the light circuits are wired.

Here a page showing the switches and indicator lights on the panel

Thanks to all who responded. As usual you've been very helpful.

Now that I know the lamp circuit is independent from the 2 poles, I will have to design my wiring for the illumination to work as I had planned.

Back to the bench
