I WILLIAM EDGE 25 Tabard Street Borough London Electrical Engineer
do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved electric switch and the same is carried out
as follows
I provide a slotted metal socket or guide preferably of copper in which a rod of:
insulated material such as fibre slides. One end of this rod of fibre which is
preferably of square section carries a metal contact preferably of copper which
make contact between two terminals when the insulated rod is operated owing to
the metallic contact end of same being forced between the terininals aforesaid by
a pivoted lever one end of which engages in a slot in the said insulated rod, the other
end terminating in a knob or button for operating same, which projects through
the movable casing. The various parts are attached to a base piece and the casing
is screwed or attached to the support carring the movable casing. A screw
engaging the insulated rod works in a slot in the socket or guide, and by operating
the said screw the freedom with which the insulated bar slides in the socket or guide
may be regulated. The section of the socket or guide is of a similar shape to the
sliding bar.

I, WILLIAM EDGE of 25 Tabard Street, Borough, London, Electrical Engineer,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to an improved electric switch and the same is carried out
as follows:
1 provide a slotted metal socket or guide preferably of copper in which a rod
of insulating material such as fibre, slides. One end of this rod of fibre which
is preferably of square section carries a metal contact preferably of copper
which makes contact between two terminals when the insulated rod is operated
owing to the metallic contact end of same being forced between the terminals
aforesaid by a pivoted lever one end of which engages in a slot in the said
insulated rod; the other end terminating in a knob or button for operating same
which projects through the movable casing. The various parts are attached to a
base piece and the casing is screwed or attached to the support carrying the
movable casing.
A screw engaging the insulated rod works in a slot in the
socket or guide & by operating the said screw the freedom with which the
insulated bar slides in the socket or guide may be regulated. The section of
the socket or guide is of a similar shape to the sliding bar.

page_text: In order that my invention may be fully understood I now refer to the annexed
drawings in which :-
Figure 1, is a plan view of my invention.
Figure 2. side elevation of same.
a is the rod of insulated material having the conducting surface b at the end of
same sliding in the sockets c & c' and having the stop pin d, for controlling the
movement of the rod a in its disconnected position e, e, are the terminals or contacts
between which the conducting end or surface passes & makes electrical contact
between same.
is a lever pivoted at g, the end k of which engages in a slot in the rod a.
his a set screw which passes through a slot in the bolt a, the head of which
engages on the top of the socket c', the screwed end of which enters the base j.
By screwing down or tightening the screw h the resistance to the movement or
speed of the bolt a through the socket c' may be controlled or regulated. The
lever is provided with the projecting knob l, by which the same is operated. m is
an enclosing casing which is screwed upon the support n carring the lever f.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
The combined arrangement of the various parts as shown in Figures 1 and 2
of the drawings and for the purpose set forth.
