Abstract
Abstract An electrical selector switch including a housing defining a spherical surface, a bearing member defining a spherical surface, and a pivotal member located between the surfaces. The pivotal member carries a spring loaded ball which engages with the surface on the housing to urge a spherical surface on the pivotal member into contact with the spherical surface on the bearing member. The bearing member being shaped to operate switches in selected positions of the pivotal member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
153 words
An electrical selector switch of the kind including a housing, a manually operable lever movably mounted on the housing and electric switches mounted within the housing and operable in selected positions of the lever, said housing being of hollow form and defining at one interior end a first substantially spherical concave surface, a bearing member located within the housing and defining a second substantially spherical concave surface opposite to said first substantially spehrical concave surface, a pivotal member located within the housing and to which said lever is connected, said pivotal member having a substantially spherical surface for co-operation with said second substantially spherical concave surface on said bearing member and spring loaded means on said pivotal member, said spring loaded means engaging with said first substantially concave surface to urge the pivotal member into contact with said second substantially spherical concave surface, said pivotal member having surfaces shaped to operate said switches.
Claim 2
Dependent Claim
153 words
An electrical selector switch of the kind including a housing, a manually operable lever movably mounted on the housing and electric switches mounted within the housing and operable in selected positions of the lever, said housing being of hollow form and defining at one interior end a first substantially spherical concave surface, a bearing member located within the housing and defining a second substantially spherical concave surface opposite to said first substantially spehrical concave surface, a pivotal member located within the housing and to which said lever is connected, said pivotal member having a substantially spherical surface for co-operation with said second substantially spherical concave surface on said bearing member and spring loaded means on said pivotal member, said spring loaded means engaging with said first substantially concave surface to urge the pivotal member into contact with said second substantially spherical concave surface, said pivotal member having surfaces shaped to operate said switches.
Claim 3
Dependent Claim
40 words
An electrical selector switch as claimed in claim 1 including a closure member secured to said housing, said closure member having an inner surface of substantially concave spherical form against which bears a complementary surface formed on said bearing member.
Claim 4
Dependent Claim
38 words
An electrical selector switch as claimed in claim 2 in which said closure member is provided with a plurality of apertures which are arranged in the manner of a gate normally associated with a vehicle gear change mechanism.
Claim 5
Dependent Claim
32 words
An electrical switch as claimed in claim 3 in which said loaded means comprises a detent member which is loaded by a coiled compression spring into contact with said first spherical surface.
Claim 6
Dependent Claim
49 words
An electrical selector switch as claimed in claim 4 in which said first spherical surface is provided with a groove in which said ball locates, said groove extending across said first spherical surface so as to guide the movement of said lever in the neutral plane of said gate.
Claim 7
Dependent Claim
32 words
An electrical selector switch as claimed in claim 5 including detents in said first spherical surface and which are engageable by said ball to locate the lever in its selected positions respectively.
Claim 8
Dependent Claim
32 words
An electrical selector switch as claimed in claim 6 including a pair of contact strips in said groove said strips being bridged by said ball when said ball is in the groove.
Claim 9
Dependent Claim
30 words
An electrical selector switch as claimed in claim 7 in which said bearing member is mounted for pitoval movement about an axis parallel to the neutral slot of the gate.
Claim 10
Dependent Claim
47 words
An electrical selector switch as claimed in claim 8 including a stop defined on said bearing member, said stop acting to prevent movement of the lever in the neutral plane from one of the selected positions until it has been moved to another of said selected positions.
Claim 11
Dependent Claim
42 words
An electrical selector switch as claimed in claim 9 including means on the lever and co-operating means on the cover to prevent movement of the lever into certain of said selected positions without a conscious effort on the part of the operator.
Claim 12
Dependent Claim
37 words
An electrical selector switch as claimed in claim 10 in which said means on the lever comprises a spring loaded sleeve movable away from the cover to disengage the sleeve from stop surfaces defined on the cover.
