DEFINITION

Classification: 337/126

(under subclass 123) Subject matter including at least one electrothermally responsive device, combined with further manual or other mechanical contact actuating means, both said device and means cooperatively acting to control the switch contacts. Usually the contacts are directly controlled by the manual or mechanical means which is in turn under the control of the temperature responsive device. However, devices in which the contacts may be opened or closed by the separate

means independently are also classified here.

(1) Note. For other manual or mechanical switch control means employed in devices of this class, see SEARCH THIS CLASS, SUBCLASS below.
