Some info about these joystick:
Instead of using conventional microswitches, Suzo Inductive sticks employ the use of a ferrite ring at the base of the joystick shaft. An oscillating magnetic field is induced in the ferrite ring by the main coil in the centre of the PCB around the opening. This oscillating field within the ferrite ring induces a current in one or more of the eight smaller coils on the PCB. The exact position of the joystick is determined by the strength of the current in each coil. A potentiometer can be adjusted so that diagonal positions are ignored (resulting in 4-way output) or that diagonals are accepted (resulting in 8-way output.) The sensitivity of 8-way operation can be refined using the potentiometer. It is completely silent and is easily switchable between 4-way and 8-way using the aforementioned pot located on the bottom plate of the joystick.
It has an octagonal restrictor to assist in locating the desired directions. There are 6 pins for the connection which are labeled on the bottom plate of the joystick: Ground/Earth; +5 VDC; Left; Right; Up; Down. It is a short throw joystick with a max travel of 5 degrees from centre. The joystick is designed to be undermounted without taking the joystick apart; this requires a hole in the panel approx 44 mm or 1 3/4". The joystick handle was produced in two sizes, a 32 mm ball handle (suitable for cocktail cabinets), and a 38 mm ball handle. This joystick is no longer produced but as of May 2006 some were still available from Groovy Game Gear and TNT Amusements.
