^ft actuating device, in particular switch "

The! Inflation concerns an actuator, in particular a switch, with a pivotable operating lever, which by means of two lateral Bearing pin between two recesses in two bearing blocks is mounted on the housing.

Such actuation devices are in particular with switches, for example, with the so-called Micro switches, known: _ Γ - .- -. .

The present furnace ^ is due to the tasks, the manufacture of such an actuator, in particular a switch, to simplify considerably and to make it cheaper ^; "■■" -... ;; ■ ""

The dismissal of the hiring is characterized in that the recess at least of a bearing block has a sehmale insertion opening to the outside through which the lever is tilted only in a Insertion position can be brought into the recesses, which, however, after tilting into the normal working position does not allow moving out, and that the actuating lever is deformable at the end in such a way that after it has taken place Inserting the lever and tilting it into the normal working position tilting the lever back into the insertion position is not possible.

Such a Sehalter mechanism has the advantage that in addition to the switch housing and the switch actuation

no other levers ^; ! Εβ ± 1 ©, such as or the like, are required. The housing used in accordance with the present furnace only requires the molding of fixed gusts for storage; des: operating lever. The operating lever consists of a straight, simple link. The installation of the: -actuating lever in the housing takes place in a very simple way, namely that it is inserted with its bearing pin in the ixissparungen and pivoted into the working division and that then: the deformable end of the lever is deformed, so that the actuation fog can no longer be brought back from the working position to the insertion position. ■ _. "

According to the present study, an actuating device is proposed which requires a minimum of axes that can be easily manufactured and assembled. _r

The hiring is explained below with the aid of an example with reference to the accompanying drawings

explained in more detail. - It shows:

In Figure 1, a switch 10 is shown, OCE so similar to the switch described in the US Patent 2,644,052 is constructed ^. It contains a housing Ί2 with a base i4, the mounting holes 16 and 18

individual is described. The: ^ eagle jacks 22 each contain an L-shaped opening 22 with a narrower one outer ö} eil; 27 and.a, widened inner Part 28. In addition, an actuator 29 is in the AbdeoKfcappe 20 provided over which the .not shown Switch mechanism is operated ... ";"; ■ ;; ■

Figure 1 also shows an "operating lever 30, the an elongated, cruciform shape, has ^ the longitudinal beam 32 is located above the actuation button 29 and depresses it when it moves in the direction of the Housing is moved. The cross-shaped lever has two crossbars 54, which serve as bearing journals and in the II-shaped openings 26 are arranged. The the other ead of the lever's longitudinal beam is at the end forked,: and the two forks 36 work with the stop steps .24 together.

Before assembly: iat jder;: operating lever 30 di © 'in figure; \ 5 shown Jorm, in which the bifurcations 36 approximately parallel to: H ^ ^ il cuptt: 4 ^{e S;} : SebelS :: run. To assemble, lever 36: seakceclri; to the working position shown in FIG. 1 into the openings 26 until the surfaces 34a of the arms 34 (see FIG. 5 ") touch the lower seams: 28a of the inner parts 28 of the openings 26, this position is shown in FIG. 2 in section" .. ■ ".;" -. Bie .-. "Width. ;;. I] M .._ Thickness' V of the arms 34 of the lever are such that they are only inserted vertically into the L-shaped openings 26 In the housing cover 20 there is provided a curved recess 20a, which is best shown in Figures 2 and 3. The width of the arms 34 and the inner portions 28 of the I-shaped openings 26 are such that the lever 3Q can be rotated from the real insertion position into the working position shown in Figure 1. Figure 3 shows the lever 30 in an intermediate position. ■■ ^: -; - ""...;':-'

One can turn the lever 30 from the insertion position beyond the working position causes the

Bar 32 the action button; 29 touches and that. the upper part 34-b of the lower arm 34 the shoulders 28b of the inner parts: 28 outer Ii-shaped openings 26 touch. This position between the upper surfaces 34b of the arms 34 and the shoulders 28b of the inner ropes 28 of the recesses is due to the lever ratios of the actuating lever 3 © opposite the actuating head 29. Because of the width of the arms 34 of the lever 30 and the lower ropes £ 7 of the: -I-shaped openings 26 will be the arms 34 in their outward movement through the Shoulders 28b of the inner ropes 28 of the L-shaped openings 26 limited. ../■■- "..

To the, operating lever ^; 30 to keep in.der in Jigur position shown 1, it is necessary _t the bifurcations to bend apart 36, as Figures 4 and show. 6 As a result, the forks 36 rest on the stop steps 24 of the cover 20, so that it is not possible to fold up the lever 30 into the positions of the Mguren 2 and 3.

Because of the relative dimensions of the trunnion serving arm parts 34 »of the inner ropes 28 and the /

outer parts 27; the E-shaped openings; ^The actuator lever 30 can only be installed in the manner shown in FIGS. 2 and 3, but after the forks 36 have been bent into the position shown in FIG. 4, the holder can no longer be dismantled
