Motorola DEK HLN1206B Schematic, Documents?

[RFI-EMI-GUY]

I intend to use one of these to remotely control power and functions for my mobile radios. I cannot find any documentation other than the DB25 pinout in the other thread.

My questions:

Do the switches illuminate when pressed? Is there backlighting as well?

What is the part number for the lens and/or inserts to label the switches?

Is there a part number for a relay box and cables to accompany this?

Does anyone have a schematic or manual?

Thanks

I have one. Don’t have any manuals on it though.
It does have a backlight. And when you press a button it does get brighter.
They absolutely need a relay. I remember asking about it years ago when I got it. The switches can only handle about 0.5amps. I ended up using it as ground side switching.

I couldn’t find any legends for them. I ended up printing them in excel. Black background with white letters. Painstakingly repeatedly printing to get get the size correct. I do not have that computer anymore unfortunately.

Let me know if you have any other questions.

That is good to know. I wondered about the backlighting. I have found various 4 to 8 relay boards from China that will provide a 10 amp form C upon a pull down. It would be nice to find something with 4 or 6 relays, plus fuse protection in a small box, otherwise I mus fabricate.

I am going to control power to all the radios via the accessory leads plus a master off switch. Normally all will come on via a Lind timer, but if need be I want to be able to kill all or some. Also need control of a VRS.

How do the momentary buttons work? Is there any logic to latch them and the light? Or do I need an external latching relay?

I was lucky about 12 years ago when I found my switchbox(s). It was a lot deal 2 DEK switch boxes and 2 fabricated relay control boards. 8 relays, all with individual fuses. Although they work for what I need, it is not what I would have done if I were to build one. Once I figured out what I was doing I sold the other one.

Your box has 2 momentary switches? There were 2 versions (the lot I got had both versions) the other has only 1 momentary (HLN-1196 I think).
There is no latching ability for them. Strictly momentary. The backlight gets brighter for the time that it is pressed, but reverts when released.
You said you have the wiring diagram, did you notice that all the switches have NO, NC, and C connections brought out through the connector with the exception of one of the switches (SW5 maybe? Can’t remember). That only has C, and either NC or NO (again, can’t remember). But not both.

Switch 4 has Com and N.O. only.

Motorola DEK HLN1206B

Okay everyone, I am back for round two of help and I hope someone can help me this time. I purchased a DEK HLN1206B from ebay. When the guy sent it to me, he send me some really large old relays and the actual connector for the wildcard box. Since i have the original connector to connect to...

👍🏻. Knew it was towards the middle.
