Definitions
- FIG. 1 shows a vertical partial longitudinal section through the switch in the basic position
- FIG. 2 shows a partial longitudinal section through the switch with the key depressed
- FIG. 3 shows a horizontal partial longitudinal section along the line III-III in FIG. 2;
- FIG. 4 shows a cross-section through the switch along the line IV.IV in FIG. 2;
- FIG. 5 shows a plan view of the switch on a smaller scale
- FIG. 6 shows a lateral view of the switch.
- the switch constructedaccording to FIGS. 1 to 4 for placing on a table has a housing 1 of bar form which is closed off on its under side by a bottom plate 2 serving as standing surface. This plate is secured by means of screws 3 to counter-sunk corner projections 4 of the housing.
- the cover of the housing 1 is provided with a longitudinal slot 5 in which a press key 6 of strip form is guided.
- On each of these spindles there is rotatably mounted a rotating member 10, 10' respectively acting as bell-crank lever.
- the lever arm 11, which swings about the horizontal middle position of each of the two rotating members 10 and 10' is articulatedly connected by spindle journals 12 with the press key 6, and the lever arm 13, which swings about the vertical middle position, of each of the two rotating members 10, 10' is articulatedly connected by joint journals 14 with an operating rod 15 extending in the longitudinal direction of the housing 1, which rod is guided between the bearing pieces 7, 7' and the rotating members 10, ,10'.
- the foot-shaped end 15 of the operating rod 15 is cranked off towards the axis of the contact button 16 of a conventional press switch 17 which is clamped in between the prongs of a retaining fork 18 seated on the bottom plate 2 of the housing 1.
- Two cutaway portions 19, 19' of the press key 6 permit unhindered movement of the latter in relation to the projections 8, 8 and thespindle journals 14 which protrude slightly into the cutaway portions.
- the switch as described is of course suitable also for pedal operation, especially where the immediate find ing of small switch knobs is difficult.
- an operating rod being displaceable beside and extending in the longitudinaldirection of the press key
- said key being effective to rotate said rotatable members for'displacing the operating rod in a longitudinal direction thereby operating the press switch
- An electric switch comprising:
- a housing having a bar form with support projections extending inwardly
- a press key having a strip form for upward and downward movement within the housing
- said press key having cutaway portions into which the support projections andarticulation journals partially proturde.
- An electric switch comprising:
- a housing having a bar form with stationary supports extending inwardly,
- a press key having a strip form which protrudes partially from the housing and is mounted for upward and downward movement within the housing
- an operating rod being disposed beside the key for displaceable movement along the longitudinal axis of the rod
- each rotating member carries two spindle journals that are parallel with respect to the axis of rotation of the rotating member
- 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.
- An electric switch comprising:
- a press key having a strip form which protrudes partially from the housing and is mounted for upward and downward movement within the housing
- an operating rod being disposed beside the press key for displaceable movement along the longitudinal axis of the rod
- 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.
- An electric switch comprising:
- a switch operating means displaceably mounted within the housing to operate the press switch
- press key means includes an elongated strip form element extending along the length of the housing.
