The joystick assembly comprises an ergonomically shaped, hand-holdable housing. The joystick shaft passes through an upper face of the housing and the lower end of the shaft is pivotably received in a ball and socket joint. The shaft is pivotable about the joint such that an intermediate portion of the shaft can engage a selected one, or a selected two, of an array of four microswitches each arranged for completing electrical connection to a VDU display. The shaft is biassed towards the neutral position solely by the four microswitches.
