Yard Siding Bit-switch

The Yard BitSwitch is used to prevent equipment entering the "Main Line" when the exit turnout is closed. When
the turnout is closed any train approaching the main line will observe a red signal and brake to a stop until the exit
turnout is thrown at which time the signal will display green and the train will be allowed to enter the "Main Line".
If there is an additional Block BitSwitch installed before the "Yard Siding" the "Release" is connected to terminal 3
of that Block BitSwitch.
The Yard BitSwitch can be used with twin coil or Bi-polar turnout motors. The power connections to the turnout
motor must be connected to the "From Turnout" terminals on the BitSwitch.
For Bi-polar motors connect one lead to the "minus terminal" and another to either "plus" terminal.
Note: If the Yard BitSwitch releases the train when the turnout is "CLOSED" reverse the leads.
For twin coil turnout motors connect the common power lead to the "minus terminal" and the other power leads to
the 2 "plus terminals"
Note: If the Yard BitSwitch releases the train when the turnout is "CLOSED" reverse the "plus" leads.
