Re: [z_scale] New Set
> Do the switches use AC or DC? and what voltage...The solenoids inside the turnouts don't care if the voltage is AC or DC. The
most commonly used power source is the AC accessory power on a power pack,
nominally 14-18 volts. They also work fine on 25-28 volts from capacitor
discharge circuits as well. Obviously, voltage is not a critical issue.
The key is *how long* you apply power, no matter the power source. Anything
over a very short fraction of a second of applied power puts the turnout at
risk of being burned up from heat in the solenoid coil. While this is true
in all scales, it is more important in Z scale given the ultra small wire
that the solenoids are made with.
