      Input: 120VAC.  60 Hz.  30 Watts  
      Output: 12VAC. 20 Watts  Built for the USA. Circuit-Breaker Portected. Indoor use only 
      This transformer should not be used on less than 10 grain of wheat bulbs for very long. To much power. 
1 Lead in wire, CK1008-1, with Switch in line. 
      Unplug when not using, even if there were a switch in line it does not shut off the transformer. 
      Transformer will stay warm and uses power. The switch will only turn off the current to the house. 

These products work in conjunction with other Cir-Kit components to wire a dollhouse or project. 

These products are from my own collection, now downsizing. I hope you are having as much fun as I had working with miniatures. Wiring can be very frustrating and stressful. Take you time, make practice boards and learn what you can before working on your final project. You will be more confident and successful with a little practice. 

My listing have been stored in a dry, smoke and pet free environment. 

Please call me if you have any questions about my listings. 

I do have 2 ebay, miniature only sites; please check them out often, I am listing all the time.
