Abstract
Abstract A cable activated switch comprising a switch support body having a through bore. A first switch contact member is retained on the body. A second switch contact member is further slidingly retained on the body and insulated therefrom. Clamping means are provided for securing the cable passing through the bore. First resilient means are provided to bias the contact members. The first and second contact members are displaced relative to each other by predetermined axial movement of the cable which passes through the support body.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
204 words
A cable activated switch comprising a switch support body having a through bore, a first switch contact member retained on said body, a second switch contact member slidingly retained on said body and insulated therefrom, clamping means for securing a cable extending through said bore, said clamping means having a circular body member with a tapered outer surface portion and a threaded outer portion, said cable extending in a through bore in said body member, at least one transverse bore extending from said tapered outer surface to said through bore, a ball in said transverse bore, said ball being of larger diameter than the depth of said transverse bore, a cylindrical locking sleeve having a tapered inner surface portion and threaded inner portion, said tapered inner surface portion extending substantially parallel to said tapered outer surface so that when said locking sleeve is threaded on said body said tapered inner surface will push said ball into said transverse bore to squeeze said cable on the through bore wall and rigidly retain said cable in said through bore, first resilient means for biasing said contact members, said first and second contact members being displaced relative to each other by predetermined axial movement of said cable.
Claim 2
Dependent Claim
204 words
A cable activated switch comprising a switch support body having a through bore, a first switch contact member retained on said body, a second switch contact member slidingly retained on said body and insulated therefrom, clamping means for securing a cable extending through said bore, said clamping means having a circular body member with a tapered outer surface portion and a threaded outer portion, said cable extending in a through bore in said body member, at least one transverse bore extending from said tapered outer surface to said through bore, a ball in said transverse bore, said ball being of larger diameter than the depth of said transverse bore, a cylindrical locking sleeve having a tapered inner surface portion and threaded inner portion, said tapered inner surface portion extending substantially parallel to said tapered outer surface so that when said locking sleeve is threaded on said body said tapered inner surface will push said ball into said transverse bore to squeeze said cable on the through bore wall and rigidly retain said cable in said through bore, first resilient means for biasing said contact members, said first and second contact members being displaced relative to each other by predetermined axial movement of said cable.
Claim 3
Dependent Claim
204 words
A cable activated switch comprising a switch support body having a through bore, a first switch contact member retained on said body, a second switch contact member slidingly retained on said body and insulated therefrom, clamping means for securing a cable extending through said bore, said clamping means having a circular body member with a tapered outer surface portion and a threaded outer portion, said cable extending in a through bore in said body member, at least one transverse bore extending from said tapered outer surface to said through bore, a ball in said transverse bore, said ball being of larger diameter than the depth of said transverse bore, a cylindrical locking sleeve having a tapered inner surface portion and threaded inner portion, said tapered inner surface portion extending substantially parallel to said tapered outer surface so that when said locking sleeve is threaded on said body said tapered inner surface will push said ball into said transverse bore to squeeze said cable on the through bore wall and rigidly retain said cable in said through bore, first resilient means for biasing said contact members, said first and second contact members being displaced relative to each other by predetermined axial movement of said cable.
Claim 4
Dependent Claim
204 words
A cable activated switch comprising a switch support body having a through bore, a first switch contact member retained on said body, a second switch contact member slidingly retained on said body and insulated therefrom, clamping means for securing a cable extending through said bore, said clamping means having a circular body member with a tapered outer surface portion and a threaded outer portion, said cable extending in a through bore in said body member, at least one transverse bore extending from said tapered outer surface to said through bore, a ball in said transverse bore, said ball being of larger diameter than the depth of said transverse bore, a cylindrical locking sleeve having a tapered inner surface portion and threaded inner portion, said tapered inner surface portion extending substantially parallel to said tapered outer surface so that when said locking sleeve is threaded on said body said tapered inner surface will push said ball into said transverse bore to squeeze said cable on the through bore wall and rigidly retain said cable in said through bore, first resilient means for biasing said contact members, said first and second contact members being displaced relative to each other by predetermined axial movement of said cable.
Claim 5
Dependent Claim
42 words

Claim 6
Dependent Claim
80 words
A cable activated switch as claimed in claim 2, wherein said switch support body is an elongated tubular body, said first and second switch contact members being positioned about said body and held in spaced apart relationships by said second resilient means said second resilient means being a helical spring abutting at opposed ends with a respective one of said contact members and at least one of its ends being in electrical insulating abutment with one of said contact members.
Claim 7
Dependent Claim
46 words
A cable activated switch as claimed in claim 3, wherein said first resilient means is a helical spring abutting at one end with said second switch contact member and electrically insulated therefrom and abutting at its other end with a stationary member located about said cable.
Claim 8
Dependent Claim
74 words
