Abstract

A tilt detecting apparatus comprises an opaque rigid ball (13) located within a two part housing (11, 21) and mounted on concave surface (12) to roll relative to the housing as the housing is tilted. The housing supports a light source (22) and a light responsive detector (15), the ball being arranged in relation to the source and detector so as to vary the amount of light reaching the detector in relation to the tilt of the housing. <IMAGE>
