My present invention relates to improvements
in switches of the type shown in my Patent No.
2,119,146, issued May 31, 1938. Such switches
comprise conducting elements and switch ele
ments inside of a non-frangible casing of rubber
or a rubber-like material and my purpose is to
provide means for insuring: proper‘action of the
switch, even if there should be a tendency on the
part of’ the casing to‘ deteriorate or soften to .a

ci?c description of structure set forth above may
be departed from without departing from the
spirit of this invention as set forth herein and
in the appended claims.
Havingnow described my invention, I claim:
1. A switch of the character described having
a hollow insulating wall, one portion of which
may be ?exed to cause opening. and closing of the
switch, the body of the switch housing having a
10 conductor embedded therein which comprises two

functional or partly so. A further object of my
separated parts, a switch element having an
invention is to provide a spring which will help

the housing of the switch to maintain its normal

switch element and the second portion of said
part hereof, .
