Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
155 words
An electric switch comprising: a. a housing having a bar form with stationary supports extending inwardly, b. a press key having a strip form which protrudes partially from the housing and is mounted for upward and downward movement within the housing, c. said key extending approximately over the length of the housing, d. a press switch mounted in the housing, e. an operating rod being displaceable beside and extending in the longitudinal direction of the press key, and f. at least two rotatable members having spindles and acting as bell-crank levers being mounted on the stationary supports and articulatedly connected to the operating rod, g. said key being effective to rotate said rotatable members for displacing the operating rod in a longitudinal direction thereby operating the press switch, h. said stationary supports having laterally protruding bearing projections for supporting said spindles, i. said key having cutaway portions which bridge oveR the laterally protruding bearing projections.
Claim 2
Dependent Claim
155 words
An electric switch comprising: a. a housing having a bar form with stationary supports extending inwardly, b. a press key having a strip form which protrudes partially from the housing and is mounted for upward and downward movement within the housing, c. said key extending approximately over the length of the housing, d. a press switch mounted in the housing, e. an operating rod being displaceable beside and extending in the longitudinal direction of the press key, and f. at least two rotatable members having spindles and acting as bell-crank levers being mounted on the stationary supports and articulatedly connected to the operating rod, g. said key being effective to rotate said rotatable members for displacing the operating rod in a longitudinal direction thereby operating the press switch, h. said stationary supports having laterally protruding bearing projections for supporting said spindles, i. said key having cutaway portions which bridge oveR the laterally protruding bearing projections.
Claim 3
Dependent Claim
97 words
An electric switch comprising: a. a housing having a bar form with support projections extending inwardly, b. a press key having a strip form for upward and downward movement within the housing, c. said press key extending approximately over the length of the housing, d. a press switch mounted in the housing, and e. an operating element movable connected to the key by articulation journals to operate the press switch when the press key is depressed downwardly in said housing, f. said press key having cutaway portions into which the support projections and articulation journals partially proturde.
Claim 4
Dependent Claim
97 words
An electric switch comprising: a. a housing having a bar form with support projections extending inwardly, b. a press key having a strip form for upward and downward movement within the housing, c. said press key extending approximately over the length of the housing, d. a press switch mounted in the housing, and e. an operating element movable connected to the key by articulation journals to operate the press switch when the press key is depressed downwardly in said housing, f. said press key having cutaway portions into which the support projections and articulation journals partially proturde.
Claim 5
Dependent Claim
164 words
An electric switch comprising: a. a housing having a bar form with stationary supports extending inwardly, b. a press key having a strip form which protrudes partially from the housing and is mounted for upward and downward movement within the housing, c. said key extending approximately over the length of the housing, d. a press switch mounted in the housing, e. an operating rod being disposed beside the key for displaceable movement along the longitudinal axis of the rod, and f. at least two rotating members acting as bell-crank levers being mounted on the stationary supports, g. each rotating member carries two spindle journals that are parallel with respect to the axis of rotation of the rotating member, h. each rotating member including a first lever arm articulatedly connected by one of the spindle journals to the press key for swinging about a horizontal middle position and a second lever arm articulatedly connected to the operating rod for swinging about a vertical middle position.
Claim 6
Dependent Claim

Claim 7
Dependent Claim
105 words
An electric switch comprising: a. a housing having a bar form, b. a press key having a strip form which protrudes partially from the housing and is mounted for upward and downward movement within the housing, c. said key extending approximately over the length of the housing, d. a press switch mounted in the housing, e. an operating rod being disposed beside the press key for displaceable movement along the longitudinal axis of the rod, and f. rotating members acting as bell-crank levers mounted in the housing to convert the movement of the press key into a movement direction of the operating rod tranverse thereto.
Claim 8
Dependent Claim
105 words
An electric switch comprising: a. a housing having a bar form, b. a press key having a strip form which protrudes partially from the housing and is mounted for upward and downward movement within the housing, c. said key extending approximately over the length of the housing, d. a press switch mounted in the housing, e. an operating rod being disposed beside the press key for displaceable movement along the longitudinal axis of the rod, and f. rotating members acting as bell-crank levers mounted in the housing to convert the movement of the press key into a movement direction of the operating rod tranverse thereto.
Claim 9
Dependent Claim
77 words
