DEFINITION

Classification: 337/82

(under subclass 37) Subject matter including significant details of means whereby the operative current value, or

range of values, sufficient or necessary to actuate the main contact control means and thereby produce an opening or closing thereof action is predeterminedly fixed, varied at will or calibrated.
