A touchpad stylus includes a housing, a stylus member axially moveable in the housing, and an energy-absorbing cushion member interposed between a rear extremity of the stylus member lightly forwardly biasing the stylus member relative to the housing. The stylus member has a smoothly spherical tip extremity, and the device avoids impact damage to fragile outer membranes of existing touchpad devices because the full mass of the housing is isolated from impact with the touchpad, the stylus member itself having very significantly less mass than an aggregate mass of the complete assembly.
