Abstract (en)
An indicator comprises a shutter 20 having apertures 32 arranged to denote settings of the control passing over a light diffuser 34. The shutter 20 is coupled to an actuator 24 of the control by a lost motion mechanism comprising springs 56 arranged in peripheral grooves 52 of the actuator between the ends of the grooves and side walls of lugs 54 of the shutter 20. The shutter is held in a desired setting position by a detent spring 48, but as the actuator 24 is rotated, springs 56a, 56b are loaded until they overcome the detent force, so as to flick the shutter to the next setting position under spring force. <IMAGE>
