Switch operating mechanism

Claim 2

A switch operating mechanism comprising: a base plate provided with an opening; an operating member pivotably accommodated in said opening; a bearing member projecting from a portion of a bottom surface of a base plate near said opening and overlying said opening; a pair of supporting members with grooves, said supporting members projecting in opposite directions from said operating member, the distance between outer surfaces of said supporting members being larger than the width of said opening; a shaft member located between said bearing member and said bottom surface of said base plate and across said opening for rotatably engaging said grooves of said supporting members when said operating member is mounted; and an actuator operated by said operating member for actuating a switch mounted on said base plate.

Claim 3

A switch operating mechansim according to claim 1 which further comprises a pair of bearing recesses formed on the periphery of said opening and on said bottom surface of said base plate, said bearing recesses receiving said pair of supporting members.

Claim 4

A switch operating mechanism according to claim 1 wherein said grooves of said supporting members take the form of a letter U adapted to engage said shaft.

Claim 5

A switch operating member according to claim 1 which further comprises a pair of projections disposed on the bottom surface of said base plate for supporting opposite ends of said shaft, said shaft being clamped between said bearing member and said projections.

Claim 6

A switch operating mechanism according to claim 1 wherein said shaft is clamped between said base plate and said bearing member.

Claim 7

A switch operating mechanism according to claim 1 wherein said bearing member is provided with a bearing in the form of an arcuate or U shaped groove for receiving said shaft.

Claim 8

A switch operating mechanism according to claim 1 wherein said switch comprises a two contact driving type seesaw switch.

Claim 9

A switch operating mechanism comprising: a base plate provided with a plurality of juxtaposed openings; a plurality of operating members pivotably accommodated in said respective openings; a plurality of bearing members, each projecting from a portion of a bottom surface of a base plate near each of said openings and overlying said respective openings; a plurality of a pair of supporting members with grooves, said supporting members projecting in opposite directions from each of said operating members, the distance between outer surfaces of said supporting members being larger than the width of said respective openings; shaft means located between each of said bearing members and said bottom surface of said base plate and across each of said openings for rotatably engaging said grooves of said supporting members when said operating members are mounted; and a plurality of actuators each operated by respective ones of said plurality of operating members for actuating respective ones of a plurality of switches mounted on said base plate.

Claim 10

A switch operating mechanism comprising: a base plate provided with a plurality of juxtaposed openings; a plurality of operating members pivotably accommodated in said respective openings; a plurality of bearing members, each projecting from a portion of a bottom surface of a base plate near each of said openings and overlying said respective openings; a plurality of a pair of supporting members with grooves, said supporting members projecting in opposite directions from each of said operating members, the distance between outer surfaces of said supporting members being larger than the width of said respective openings; shaft means located between each of said bearing members and said bottom surface of said base plate and across each of said openings for rotatably engaging said grooves of said supporting members when said operating members are mounted; and a plurality of actuators each operated by respective ones of said plurality of operating members for actuating respective ones of a plurality of switches mounted on said base plate.

Claim 11

A switch operating mechanism according to claim 8 wherein said shaft is common to said openings, and wherein said grooves of said supporting members take the form of a letter U adapted to engage said shaft.

Claim 12

A switch operating mechanism according to claim 8 wherein said each of said switches comprises a two contact driving type seesaw switch.

Claim 13

A switch operating mechanism according to claim 8 wherein each of said bearing members comprise a letter T shaped shaft supporting member with one leg extending in the longitudinal directions of said openings for supporting said shaft which is engaged by said supporting members of respective ones of said operating members and said bearing members.

Claim 14

A switch operating mechanism comprising: a base plate provided with an opening; an operating member pivotably accommodated in said opening; a bearing member projecting from a portion of a bottom surface of a base plate near said opening and overlying said opening; a pair of supporting members projecting in opposite directions from said operating member, the distance between outer surfaces of said supporting members being larger than a width of said opening; an engaging member having a projection extending downwardly from the botton surface of said operating member and located near said opening, said projection rotatably engaging said bearing member when said operating member is mounted; and an actuator operated by said operating member for actuating a switch mounted on said base plate.

Claim 15

A switch operating mechanism comprising: a base plate provided with an opening; an operating member pivotably accommodated in said opening; a bearing member projecting from a portion of a bottom surface of a base plate near said opening and overlying said opening; a pair of supporting members projecting in opposite directions from said operating member, the distance between outer surfaces of said supporting members being larger than a width of said opening; an engaging member having a projection extending downwardly from the botton surface of said operating member and located near said opening, said projection rotatably engaging said bearing member when said operating member is mounted; and an actuator operated by said operating member for actuating a switch mounted on said base plate.

Claim 16

A switch operating mechanism according to claim 12 wherein said projection is provided by a rear end of said operating member.
