The limit switch device has small overall dimensions due to a close-packed arrangement of the set (30) of step-down gears, which are assembled on at least two pins to obtain very high step-down ratios. Inside the casing, made up of a base (10) and of a cover (80), there is an intermediate plate (60) with a flat surface (62) on which there are at least two projecting couplers (52, 46) to drive operating components (70, 72 ...) that can be quickly assembled in different combinations by using seats designed for this purpose. The toothed wheels of such an assembly (30) can mate each other by means of hubs having polygonal joints (23, 34, 39), which are discrete or integral with other elements such as the said couplers, and which make the assembling easier. <IMAGE> |
