I am wiring up a Rocker Switch. https://www.digikey.com/product-detail/en/cw-industries/GRB260A401BBRN2/CW119-ND/2349699

It is connected to pin 2, 3, and 4. I couldnt find the information on the data sheet. What is the wiring for this switch? How should I wire this switch?


The function is in the first diagram in the series document.

The circuit for the lamp is located in the drawing.

I cant get the LED lamp to turn on when on. I think the switch is working fine. Just having problems with the lamp.

This is the power supply I am using: https://www.digikey.com/product-detail/en/mean-well-usa-inc/LRS-200-12/1866-3330-ND/7705022

How exactly do you have this wired? The illumination voltage is 250VAC on the CW119-ND as it is a Neon and not an LED.

I have the 12V power supply I mentioned above. As well as a 12/24V converter. I’m not sure of the part number on DigiKey but it is: https://www.amazon.com/BINZET-Converter-Regulator-Regulated-Transformer/dp/B00J3MHRNO/ref=asc_df_B00J3MHRNO/?tag=hyprod-20&linkCode=df0&hvadid=228860412633&hvpos=1o1&hvnetw=g&hvrand=8052238142636140916&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1016367&hvtargid=pla-391265192059&psc=1

The (-) of the power supply is connected to the (-) of the converter. The (+) on the power supply is connected to pin 3 of the switch. The (+) on the converter is connected to pin 2 on the switch. Pin 4 on the switch is connected to ground of the power supply.

So functionally the switch will operate at the lower voltage across pins 2/3, however the neon will only light with 250VAC.

Hi @andrea.michael,

As Robert said, the neon lamp within that switch requires a high voltage load (120Vac or higher) to illuminate. Therefore, it would only illuminate if connected on the AC input side of your power supply, not the 12V DC output side.

If you want a switch to light up on the 12V DC side, you will need to use a different switch.

Here is essentially the same switch with a 14V nominal (12V will suffice) incandescent lamp:

If you prefer LED indication and can tolerate a different form-factor, we have a round type rocker switch which will handle your current requirements and light up with 12V in the following part number:
