Description

GERMAN

The invention relates to a waterproof toggle switch with an additional operating rocker arm, which is used to guide the rocker arm of the switch insert is provided with a recess and is pressed sealingly against the opening of the housing cover by spring pressure, its circular segment-shaped Place shoulders against the corresponding guideways in the inside of the lid. Such waterproof toggle or rocker switches are already become known; in these, the switch insert is also sealed in the housing still by a clamped between the housing cover and the housing lower part, on the inner rocker arm mounted membrane, while the outer rocker arm by means of a compression spring against support surfaces of the Lid slot is pressed. However, the rocker arm provided there must be used to support the compression spring and be specially designed to hold the membrane. Furthermore, there when removing the cover the spring and the outer rocker arm fall out, making assembly and connection of the Switch are difficult.

Toggle switches have also become known where between the switch insert and the Cover a spring-loaded rubber ring is clamped, which is a spherical part of the inner rocker arm sealingly encloses at the cover slot, while an outer rocker switch on the stump of the inner rocker arm is screwed on. Even with this type of sealing, neither a normal, complete Toggle switch insert can be used, nor are the sealing elements self-retaining in the cover. The membranes which are also known are to be avoided according to the invention, since they become after some time can easily become brittle and unusable.

The invention is now based on the object of a waterproof toggle switch with a normal To use toggle switch insert, which is inserted into the lower part of the housing, fastened there and after the Fastening by placing a housing cover with a second rocker arm against moisture is protected, the second rocker arm, which overlaps the normal rocker arm of the insert and leads, is not only stored watertight in the lid, but is also held there.

The solution to this problem is that the outer rocker arm made of soft material by means of a plate fastened to the inside of the cover by means of screws and by means of the plate supporting itself Springs held in the lid and pressed with its two shoulders against its guide surfaces is, the plate for the passage of the normal rocker arm of the switch insert a Has slot and the recess of the outer

have been named as inventors

Rocker arm is adapted to the shape of the normal rocker arm.

This arrangement allows an extremely simple switch structure with an exchangeable switch insert and easy assembly, since when removing the cap to, for. B. to connect the switch, none loose parts can fall out, but all parts are connected to the lid.

An embodiment is shown in the drawing, namely shows

Fig. 1 the toggle switch in a side elevation, partly in section,

Fig. 2 the same in elevation, partly in section.
The commercially available toggle switch, consisting of base α with the switching mechanism parts and the rocker arm b, is fastened in the lower part of the housing c, as is known per se, with the cover d of the housing on the lower part c, namely on the upper edge of the same, As is known per se, by arranging a sealing ring e, which is made of rubber or the like. Is placed.

In order to actuate the rocker arm b of the switch insert, according to the invention, a further, made of soft material, outer rocker arm g is arranged in the rear face / of the cover d, which is expediently arched outward, which is secured by an inside on the cover d by means of screws η fixed plate m and held by springs I supported on the plate in the lid and is pressed with its two shoulders k against its guide surfaces.

In the plate m a slot is arranged for the passage of the normal rocker arm b of the switch insert α.

The recess of the outer rocker arm g is adapted to the shape of the normal rocker arm b.

The fact that the rocker arm g with the shoulders k is pressed against the inside of the cover d by means of springs I , the springs / being supported on the metal plate m, which are fastened by means of screws, is an absolutely good and secure seal for the cover slot achieved, which is thus protected against the ingress of moisture and water; in addition, simple manufacture and easy assembly is achieved by using less extremely simply designed components.
