Bite Switch

An assistive input device consisting of a small button held in the mouth and activated by biting down on it, used by people with severe motor impairments who cannot operate hand-held controllers or switches. Bite switches are commonly used alongside joysticks or sip-and-puff devices by individuals with tetraplegia or other conditions affecting upper limb function. In gaming and computer access, a bite switch can serve as a button press, enabling users to trigger actions, make selections, or control game mechanics that would otherwise require hand-operated buttons.
