Abstract
A limit switch consisting of a driven member connected to a rotary driver member the operation of which is controlled by the limit switch, so as to turn therewith, one or more poles geared to the driven member so as to be rotated thereby, one or more fingers extending laterally from each of the poles, and one or more electric switches mounted adjacent each pole so as to be engaged and operated by one of the fingers at one position in the angular movement of the pole. The gear connection between the driven member and the poles is disengageable by manual means and readily adjustable to provide a coarse setting of the relative angular positions of the driver and poles, and the extension of the fingers from the poles is continuously adjustable to provide a fine setting. The ratio of the gears is such that the poles turn faster than the driver. This multiplies the motion of the fingers and hence provides greater accuracy in the operation of the switches.
