Switch joysticks are distinguished from most wheelchair joysticks by their output type. While standard wheelchair joysticks typically offer proportional output, meaning that the speed and direction of the wheelchair's movement varies relative to the degree of joystick displacement, switch joysticks operate differently. They function by using discrete switches that activate specific functions or directions without the ability to vary the output based on the degree of movement or pressure applied. This makes them suitable for users who may have limited motor control or who find it difficult to manipulate a traditional joystick.

In contrast, options that pertain to durability or the amount of strength required to operate do not directly compare the fundamental operational differences between switch and conventional joysticks. The focus on the nature of the output—whether proportional or switch-based—is essential for understanding how these devices cater to different user needs in assistive technology.
