DEFINITION

Classification: 338/81

(under subclass 80) Subject matter wherein one of the terminals or electrodes is removable from the liquid resistance element, as by raising the electrode from the liquid element or by lowering the level of the liquid element from the electrode, thus to make and break the circuit between the liquid element and the electrode.
