ABSTRACT:
A high visibility indicator 12 for fitting to the rotatable drive shaft 11 of a rotary actuator 10 is capable of being rotated from a first position to a second position to indicate corresponding first and second positions of the actuator 10. The indicator 12 has an inner cylindrical member 13 fitted to the shaft 11, an outer cylindrical member 15 secured to the housing 10 of the actuator 10, and a sleeve member 17 interposed between members 13, 15 and drivingly connected to each via pin and slot connections 15A, 19, 14A, 18, which are arranged so that rotary movement of inner member 13 produces axial movement of sleeve member 17. The members 13, 15, 17 have color-coded surfaces arranged such that when the sleeve member 17 is at one end of its axial travel, a first color-coded arrangement is visible and when the sleeve member 17 is at the other end of its axial travel, a second color-coded arrangement is visible.
