Joystick Knob Foam Ball Ø39 mm for R-net/VR2/VSI

The Joystick Knob Foam Ball Ø39 mm is an alternative joystick knob for control systems from the R-net, VR2 and VSI series. These systems are developed by PG Drives Technology and are used on powered wheelchairs.

The knob has a diameter of approximately 39 mm and is intended for finger operation. It is made from a very open foam structure that compresses and shapes itself to the fingertips while driving. This creates a softer touch and more comfort compared with standard hard plastic joystick knobs.

This version is mainly chosen by users who find the hard or smooth surface of a standard knob uncomfortable, while still having sufficient hand function to steer with their fingers.

Where a larger softball knob supports operation with the palm and gross motor skills, the foam ball focuses on comfort and tactile feedback during finger control and more precise movements. Therefore, it is frequently used in individual adaptations and rehabilitation environments.

Important notice

This joystick knob is designed as a comfort alternative to the standard knob. When used on very lightly adjusted joystick modules, the changed grip and return behaviour should always be evaluated during individual fitting.
