ArcadeJoystick with 4-way to 8-way powered restrictor switching
motorised joystick

Motor-driven restrictor plate switches between 4 and 8 way in less than a second
USB Servo Control board drives two joystick servos.
Can also be switched in a standalone setup (no PC) using two buttons or a toggle switch
Multiple control boards can be used on one PC for 4 or more players
Optional RGB Illuminated handle available.

  • At last! Full mechanical 4-8 way restriction with powered switching.
  • Separate control board plugs into a USB port and controls the servos on two joysticks.
  • Comprehensive software support including test utility and a special utility which can be command-line or GUI driven.
  • Integrated into the Ultimarc DLL which provides API calls to perform switching, for front-end developers.
  • No separate power required. Takes power from USB port
  • Hardware mode also allows switching using two buttons or a toggle switch.
  • Switches are connected in the same way as a standard joystick, to a suitable interface such as an I-PAC.


The ServoStik consists of three parts:

Base Joystick:

This is installed and wired to an interface in the same way as any standard arcade stick. Mounting method depends on panel design, material and thickness. Our blind-hole mounting kits can be used on wood panels of thickness 5/8 in or greater.


The motor baseplate mounts using two of the same mounting screws as the base joystick. NOTE; The two screws shown in the pictures above, which secure the motor baseplate to the joystick are NOT INCLUDED as these are part of the joystick mounting hardware.

Control Board

 The control board can be mounted to the motor baseplate of one of the two sticks using supplied mounting hardware. Wires from each motor need to be connected to the screw terminals. One control board drives two motors. A four-player panel will require two control boards.

Software Support

Test Application


This simple application can be downloaded here.
It simply has two GUI buttons for switching to 4-way or 8-way. All detected control boards (and therefore pairs of sticks) are switched.
The app is also used for PERMANENTLY switching to hardware mode (see below).


This application can be downloaded here: It supports both the ServoStik and our Ultrastik 360

Running JoyTray from command line:

JoyTray.exe -servo [joy4way|joy8way]
(If using Ultrastik 360: JoyTray.exe -u360 [mouse|analog|joy8way|easyjoy8way|joy4way|djoy4way|rdjoy4way|joy2way|vjoy2way])
If you add an -exit argument the program will exit without staying resident.
Until front-end developers add native support for the ServoStik, this is the way to automate switching. The front-end needs to be configured to run a command line before starting games eg:
JoyTray.exe -servo joy8way before all 8-way games
JoyTray.exe -servo joy4way before all 4-way games

JoyTray Hotkeys:

When resident: F4 switches to 4-way and F8 switches to 8-way.  You could assign I-PAC-connected controls to these keycodes. Maybe use I-PAC shifted codes.

JoyTray GUI Mode:

Launch JoyTray.exe by itself and it will show an icon in the tray which can be right-clicked to show a menu. It will gray out the U360 or ServoStik menu items based on whether you have them attached. There is an option to run the program at startup.

Third-PartySoftware and SDK Support

As most third-party software and our SDK is cross-product, we have placed all details on this page.

Hardware Mode

This special mode is used when there is no PC and you need to switch the stick using a toggle switch or two buttons.

The control board can be placed into hardware mode using the test application (see above). Note this change is PERMANENT.
Switching between 4 and 8 way is done using either two buttons or a toggle switch.

To connect the buttons, cut the A plug from the USB cable and strip the wires.
Connect the RED wire to a 5 volt source. (JAMMA power supply for example)
Connect the BLACK wire to Ground on the power supply
Connect the Green wire to the NO contact of a pushbutton for 4 way
Connect the White wire to the NO contact of a pushbutton for 8 way
Connect the COM connections of both buttons to the black daisy-chain wire which runs to all other controls, or to the power supply ground.

Alternatively you can use a toggle switch with the center connection to ground and the end connections to the green and white wires.
