DEFINITION

Classification: 335/22

(under subclass 21) Subject matter wherein the significant latching or tripping structure comprises two or more separate means, whereby the contacts are maintained in a closed position until released or whereby the latching means is released and the contacts allowed to open, and each acting independently of the other. Devices in which the latching means comprises a main latch under the control of an auxiliary latch and in which the actuation of the main latch depends upon the condition of the auxiliary latch will not be found here but in the generic subclass 21 above.
