My pair of Lionel 1122E Switches activate fine at ~12 volts using a ZW Postwar Transformer. Does anyone know what the amperage draw is on the ZW (set at 12 volts) from these switches while they are:

I will guess the bulb draws 300 miliamps (.03 amps) and the coil draws .5 amp or less when energized. Again, just a guess based on my electronics knowledge.
Thanks for your response. So if my Postwar ZW is set at 12 volts and each 1122E Switch draws ~0.53 amps when energized, am I correct in saying that the power (in watts) used by each 1122E Switch, when energized, is approximately 6 watts?
Yes, volts x amps = watts or VA=W
You can get an accurate reading by using a digital volt meter that has amperage readings, putting the meter in series between the transformer terminal and the turnout terminal.
Thank You.
Your draw is all the light bulbs added together. You pretty much only activate one switch at a time and that is only momentarily.
Add the bulbs on the controller to the equation.
Thanks for the responses.
