Abstract
Abstract A control member for a contact device, comprising a first stationary cylinder of elastically compressible material, in which a second cylinder of the same material is coaxially arranged for movement with respect to this first cylinder by means of an elastically compressible annular coupling. The two cylinders and the coupling are constructed to form one integral unit. The coupling comprises a comparatively rigid centre portion which is connected by comparatively flexible portions to the cylinder, and cooperates with a pressure edge provided on the inner cylinder.

Claim 4
Dependent Claim
171 words
A control member for a contact device comprising a hollow relatively rigid first body of elastic compressible material, a second relatively rigid body of elastic compressible material coaxially arranged with respect to said first body, a compressible coupling connecting said first body with said second body so that said second body is axially displaceable for contact movement with respect to said first body, said first body said second body and said compressible coupling forming a single integral unit, a flexible diaphragm carried by said second body, a pressure member carried on said flexible diaphragm, said compressible coupling comprising a rigid portion, a first flexible portion connecting one side of said rigid portion to said first body, and a second flexible portion connecting the other side of said rigid portion to said second body, and a pressure edge connected to said displaceable second body engaging said rigid portion of said compressible coupling when said second body is axially displaced so as to compress said rigid portion of the coupling during contact moving.
Claim 5
Dependent Claim
23 words
