ELECTRIC SWITCHES; RELAYS; SELECTORS; EMERGENCY PROTECTIVE DEVICES (contact cables H01B 7/10; overvoltage protection resistors, resistive arresters H01C 7/12, H01C 8/04; electrolytic self-interrupters H01G 9/18; switching devices of the waveguide type H01P; devices for interrupted current collection H01R 39/00; overvoltage arresters using spark gaps H01T 4/00; emergency protective circuit arrangements H02H; switching by electronic means without contact-making H03K 17/00)
NOTE
-

Attention is drawn to the Notes following the titles of class B81 an subclass B81B relating to "micro-structural devices" and micro-structural systems"

This subclass covers (in groups H01H 69/00 to H01H 87/00) devices for the protection of electric lines or electric machines or apparatus in the event of undesired change from normal electric working conditions, the electrical condition serving directly as the input to the device.

This subclass does not cover bases, casings, or covers accomodating two or more switching devices or for accomodating a switching device as well as another electric component, e.g. bus-bar, line connector. Those bases, casings or covers are covered by group H02B 1/26.

In this subclass, the following terms or expressions are used with the meanings indicated :

- "relay" means a switching device having contacts which are
operated from electric inputs which supply, directly or
indirectly, all the mechanical energy necessary to cause
both the closure and the opening of the contacts;
- "driving mechanism" refers to the means by which an operating
force applied to the switch is transmitted to the moving
contact or contacts;
- "operating" is used in a broader sense than "actuating"
which is reserved for those parts not touched by hand
to effect switching;
- "acting" or "action" means a self-induced movement of parts
at one stage of the switching.
These connotations apply to all parts of the verbs "to operate", "to actuate" and "to act" and to words derived therefrom, e.g. to "actuation".

In this subclass, details are classified as follows :

- details of an unspecified type of switching device, or
disclosed as applicable to two or more kinds of switching
devices designated by the terms or expressions "switches",
"relays", "selector switches", and "emergency protective
devices", are classified in groups H01H 1/00 to H01H 9/00;
- details of an unspecified type of switch, or disclosed as
applicable to two or more types of switches as defined by
groups H01H 13/00 to H01H 43/00 and sub-groups H01H 35/02,
H01H 35/06, H01H 35/14, H01H 35/18, H01H 35/24 and H01H 35/42,
all hereinafter called basic types, are classified in
groups H01H 1/00 to H01H 9/00;
- details of an unspecified type of relay, or disclosed as
applicable to two or more types of relays as defined by
groups H01H 51/00 to H01H 61/00, hereinafter called basic
types are classified in H01H 45/00;
- details of an unspecified protective device, or applicable
to two or more types of protective devices as defined by
groups H01H 73/00 to H01H 83/00, hereinafter called basic
types, are classified in H01H 71/00.
However, details only described with reference to, or clearly only applicable to, switching devices of a single basic type, are classified in the group appropriate to switching devices of that basic type, e.g. H01H 19/02, H01H 75/04;

- mechanical structural details of control members of switches
or of keyboards such as keys, push-buttons, levers or other
mechanisms for transferring the force to the activated
elements are classified in this subclass, even when they are
used for controlling electronic switches.
However, mechanical details directly producing electronic effects are classified in group H03K 17/94.
