Installing electronic transformer with 3 way touch dimmer switch

No, not unless the transformers and LEDs are rated for dimming and the switch is rated for LEDs.

Look at product number again to see if numbers posted are correct.
Also include what type of device this is: rotary dimmer? slide dimmer? touch dimmer? Switch? single-pole application or 3-way? And include what you are replacing.

Your issue is that the dimmer is not rated to handle the type of fixture/lamps its controlling.

From a lighting control standpoint, the 12V-lamps classify as "low-voltage halogen" and, somewhere in that circuit, have a transformer(s) converting the 120V~ down to 12V~. Using incandescent dimmers (like the one you are using) can cause compatibility issues with those transformers. What I suspect is happening is that the incompatibily is either throwing voltage spikes or current spikes on the line which are causing the dimmer to enter some sort of "safety" mode to shut everything down before any problems occur.

My recommendation is to first figure out what type of transformer it is: Either magnetic low-voltage, or electronic low-voltage. Ideally you would contact the transformer manufacturer (or look up their specs online) to figure that out. Other rules of thumb: if the transformer's big & bulky, it's probably magnetic - conversely if its lightweight, it's probably electronic. If its only one transformer controlling all of the lamps together, it's probably magnetic - conversely if its one of those transformers where the transformer and light bulb come togheter as one assembled unit and then snap into the track, it's probably electronic.

Then make sure the dimmer is rated for magnetic low-voltage, or electronic low-voltage (depending upon what the transformer is).

If you could describe the previous lights/switches configuration and how it was changed, I think I can help solve your problem.

The switch has gon bad on you. You need to replace the dimmer switch

If each fixture has an individual transformer, the chace is that they are electronic (about the size of a matchbox car) If so, you have the wrong dimmer installed. You will need to install a MAELV (Electronic Low Voltage) Dimmer. The regular dimmers are set up for Magnetic Low Voltage and incandescent which work differently. http://www.lutron.com/TechnicalDocumentLibrary/362219.pdf

Here is a link to the difference in how they work. Also, if they are a Low Wattage light like an LED, the dimmer may not have enough resistance to bleed off the excess voltage. The MAW-600 has a minimum load of either 25 or 40 watts. If you are operating LED's you may also need a Low Wattage Interface to act as a simulated load that wires in series with your lights. (lut-lbx)

If it gets too anoying until you get the proper dimmer, you can switch the Air Gap switch at the bottom to the off position. This completely disconnects the power to the load side of the dimmer.

Good Luck

If each pendant has an individual transformer that is about the size of a hotwheel then you need a dimmer specifically for ELECTRONIC LOW VOLTAGE. A lot of electricians don't know that the different types of lights require different dimmers. Most store bought dimmers are for incandescent lights only, and some nicer dimmers like the Lutron Maestro's are rated for incandescent or MAGNETIC Low Voltage which require a different Sin wave interuption. I don't know that leviton makes a dimmer in that style for Electronic Low Voltage. You could install a Lutron DVELV300P-Wh, but that is a Decora opening. http://www.lutron.com/CMS400/WorkArea/downloadasset.aspx?id=25437
Here is a link to explain the difference in how the dimmer needs to work. Good luck!

there is not way to know how the wires are run by the description.
it is possible to connct true 3-way switch, it will required additonal pair of wires to all 3 switches (meaning 3-14/3 wire).
so call 3-way switches is only two way. I have not seems a real 3-way switches.
go to the following site. they a connection diag. for the switches.

Unfortunately, the hum is normal for operation of that type of dimmer at low levels.  Sometimes the lamp filaments will also "sing" a high pitched sound.

florecent bulbs wont dim unless they are dimmable.
