SwitchWright Board- Versaltile board for driving a servo complete with with DCC and a DPDT relay for powering the frog and other accessories. Can be controlled with a ready-to-mount fascia controller with indicator LEDs or use a toggle switch. Control panels are simple with our plug-in controller - no soldering needed.
Want DCC control? A builtin DCC stationary decoder allows you to use DCC, a pushbutton or both.
The relay switches when the servo gets to the mid-point of its travel. The servo turns off when it gets to the endpoint to prevent buzzing and drawing excessive power (or you can force it to stay on with a jumper). The servo can be set to run at 4 speeds from slow to fast. The amount of servo throw can be set to 2 values - about +/- 15 degrees and +/- 30 degrees. A jumper is used to center the servo and keep it powered while installing to make it easy adjust the servo position.
The DCC address is simple to teach - put on the address jumper (LED on fascia controller will blink), issue the switch command from your throttle at the desired address and the board will remember this address (LED will stop blinking). There are no CVs to set.
Multiple Fascia Controllers? Just use a Y cord and you can add a second controller. A second Y cord and you can have 3 controllers.
Aruduino fans will find this works nicely for them. It uses a 5volt power supply. While you can easily drive servos with an Arduino this board allows you to seperate all the complex code of running a servo, setting the positions and activating a rely from the rest of your code. All you need is a simple Digitalwrite statement and a single output from the Arduino. Another advantage is that the Switchwright can prevent servo buzzing by turning off the servo and restarting when needed. This function requires special hardware not normally available on an Arduino.
Crossover and passing sidings with single button control? You can use a Y cord to add a slave machine that will move in parallel so you can move two turnouts with one button. Ideal for controlling crossovers and passing sidings. Double crossover? Just add 3 more slaves with Y cords and all 4 points of a double crossover can be controlled with one pushbutton.
The board will mate with the SwitchWright servo bracket for which you can find files for 3D printing your own here
