Control two servos independently with 3 positions each
Speed Controllable from very slow to very fast
Drive circuitry for external LED indicators - common anode OR common cathode
Inputs for momentary pushbuttons
Bounce Simulation - blades bounce at end of throw
Variable Bounce Amplitude
DCC accessory decoder built in (can be used with JMRI PanelPro)
Anti-backlash for stub switch center position ensures accurate positioning each time
Time-delay option - simulates a signal system by turning from red to yellow to green with a time delay.
Can be used with most signaling systems such as CMRI or Logicrailtech
(Note: not for 3-way turnouts, more properly known as lap turnouts, which are actually two overlapping but independent turnouts. For those use two servos driven by singlets or half of a quad.)
The dual 3-way can be used to control 2 servos with 3 positions each. Typical uses are semaphores and 3-way stub switches. Comes with 2 I/O connectors that are used to connect to your signal system and/or indicator LEDs (or just use DCC).

Video of the Dual 3-Way on my Donner Summit layout being used to run a lower-quadrant semaphore.
Here are some shots of the coming Dual 3-Way Servo Driver being used to drive a Tomar upper-quadrant semaphore. The action is controlled by a Logic Rail Tech Signal Animator both of which can be purchased here.
Dual 3-way In Action
Here is a photo sequence showing the Dual 3-Way driving a 3-way stub switch. Thanks to Jason Reis for building the switch for me. The Hex Frog Juicer would be the ideal way to power the 3 frogs.
