Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
152 words
In a bidirectional rotary push-button switch having switch contacts rotatable in either direction through a plurality of switch positions and housed within an open-sided hollow case, and a removable side cover therefor, the combination comprising a. a rotatable gear member having teeth of a predetermined width for rotating said switch contacts in either direction within the case, b. a pair of operating members diametrically disposed on opposite sides of the axis of said gear member and laterally offset with respect to each other and mounted for independent reciprocal linear movement tangentially with respect to said gear member, c. gear-rotating means carried by each of said operating members independently and alternately engageable with the teeth of said gear member to rotate said switch contacts step-by-step in either direction, and d. means on said gear member limiting the continuous rotation of the switch contacts in either direction beyond a selected number of switch positions.
Claim 2
Dependent Claim
152 words
In a bidirectional rotary push-button switch having switch contacts rotatable in either direction through a plurality of switch positions and housed within an open-sided hollow case, and a removable side cover therefor, the combination comprising a. a rotatable gear member having teeth of a predetermined width for rotating said switch contacts in either direction within the case, b. a pair of operating members diametrically disposed on opposite sides of the axis of said gear member and laterally offset with respect to each other and mounted for independent reciprocal linear movement tangentially with respect to said gear member, c. gear-rotating means carried by each of said operating members independently and alternately engageable with the teeth of said gear member to rotate said switch contacts step-by-step in either direction, and d. means on said gear member limiting the continuous rotation of the switch contacts in either direction beyond a selected number of switch positions.
Claim 3
Dependent Claim
79 words
In a bidirectional rotary push-button switch as defined by claim 1, wherein said means on said gear member limiting the continuous rotation of the switch contacts comprises selected teeth on said gear member having a width less than that of the remaining teeth so as to be half teeth laterally offset with respect to each other and said offset operating means so as to be out of the line of movement of said gear-rotating means at predetermined switch positions.
Claim 4
Dependent Claim
56 words
In a bidirectional rotary push-button switch as defined by claim 1 wherein said gear-rotating means carried by each of said operating members comprises a trip finger yieldably disposed so as to contact one gear tooth of said gear member during its linear movement tangentially with respect thereto and rotate said gear member a predetermined angular distance.
Claim 5
Dependent Claim
84 words
In a bidirectional rotary push-button switch as defined by claim 3, wherein said means on said gear member limiting the continuous rotation of the switch contacts, comprises selected teeth on said gear member having a width less than that of the remaining teeth so as to be half teeth laterally offset with respect to each other and to said offset operating means so as to be out of the line of movement of said trip finger of either operating member at predetermined switch positions.
Claim 6
Dependent Claim
80 words
In a bidirectional rotary push-button switch as defined by claim 1 including means for supporting said gear member for rotation in either direction, said gear member being removably supported on sAid supporting means, whereby said limiting means thereon may be positioned relative to said gear-rotating means so that said gear-rotating means can only engage and rotate said gear member and the switch contacts thereon through a limited degree of rotation into and out of a selected number of switch positions.
Claim 7
Dependent Claim
84 words
In a bidirectional rotary push-button switch as defined by claim 4 including means for supporting said gear member for rotation in either direction, said gear member being removably supported on said supporting means, whereby said half teeth thereon may be positioned relative to said gear-rotating means so that said trip finger of either operating member can only engage and rotate said gear member and the switch contacts thereon through a limited degree of rotation into and out of a selected number of switch positions.
