Improvements in Electrical Switches.
I, JOHN WILLIAM FIELDING, 59 Dairy House Road Derby, Clerk, do hereby
declare the nature of this invention to be as follows:―
This invention relates to electrical switches and consists in an improved
construction of same and the same is carried out as follows:
I provide a spindle carrying a desired number of arms for making contact with
terminals so that various circuits may be used as required. The spindle carries a
number of faces, flats or projections upon which a spring locking piece engages s0
that the arms are held in the desired contact with the terminals. A thumb piece
or knob is so attached to the spindle that a certain amount of play is allowed
between the spindle & thumb piece or knob in order to ensure a quick break &
make when the spindle is being operated by the knob or thumb piece aforesaid.
By this arrangement the switch may be operated in either direction with equal
facility & the arms and contact terminals are so arranged that all contacts are
broken in a prearranged position.

This invention relates to electrical switches and consists in an improved
construction of same, and is carried out as follows.
I provide a spindle carrying a desired number of arms for making contact with
terminals so that various circuits. may be used as required. The spindle carries a
number of faces or flats or projections upon which a spring locking piece engages
80 that the arms are held in the desired contact with the terminals. A thumb
piece or knob is so attached to the spindle that a certain amount of play is allowed
between the spindle and thumb piece or knob in order to ensure a quick break
and make when the spindle is being operated by the knob or thumb piece
aforesaid.
By this arrangement the switch may be operated in either direction with equal
facility and the arms and contact terminals are so arranged that all contacts are
broken in a prearranged position.
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.

The arm or arms a engage between the contact pieces b, being carried upon the
central spindle e, which has flats, or projections d, so that the position of the arms
may be regulated said arms being split or slotted at their ends so as to form a
flexible end which engages between the slots in the terminals b, e being a knob or
thumb screw for rotating said spindle carrying the said arms a The whole being
carried upon a suitable base f. The retaining catch piece g which bears upon the
flats or 'faces d, is actuated by the springs h, which are carried upon the supports i,
so as to cause the catch piece 9 to bear upon the flats or projections.d on the
spindle e in order to retain same in the desired' position as shown so as to keep the
ends or end of arm or arms a in position in the terminals b.
Having now particularly described and ascertained the nature of my said'
invention and in what manner the same is to be performed, I declare that what I'
claim is :-
One or more arms carried upon or attached to a pivot or spindle having flats or
projections on same so that the position of said spindle may be regulated, so that
various circuits may be employed.
