Embodiment Construction

[0052] All figures are diagrammatic only and show the invention in its essential components. Wherein, the same reference numerals correspond to components with the same or comparable functions.

[0053] FIG. 1 shows an electrical switch 10 with a rotary contact system, which is similar to that in the so far unpublished German patent application "Electrical switch" (internal text) of the same applicant on January 25, 2011. Block No. 2010 24036) described in the electric switch is the same.

[0054] The rotor housing 20 is rotatable in the direction of the arrow P about the axis of rotation 40 . Contact bridges or contact bridges 30 are arranged inside the rotor housing 20 , which can also rotate together with the rotor housing 20 or relative to the rotor housing 20 in the direction of the arrow P. Axis 40 revolves.

[0055] The contact bridge 30 is formed by a first contact arm 50 and a second contact arm 51 。 Each of the two contact arms 50 and 51 is provided at its end wi...

Abstract

An electrical switch is disclosed, especially a circuit breaker. In addition, a method for improving such a switch is also disclosed. In order to protect an electrical switch in an especially simple manner from contamination and / or damage by erosion materials, it is proposed to cover a few or all functional parts of the switch at least partly with a protective material, wherein the protective material involves a viscous, temperature-resistant mass.

Description

technical field [0001] The invention relates to an electrical switch, in particular a circuit breaker or power switch. Furthermore, the invention relates to a method for improving such a switch. Background technique [0002] Electrical circuit breakers or power switches usually have a rotary contact system with two contact elements, each connected to a current path and a rotatably mounted contact element that interacts with at least one of the fixed contacts. fixed point of contact. Movable contact elements, usually designed in the form of bridges, are used to interrupt and close electrical circuits. For example, the operating mechanism designed as a rocker structure is used for manual switching on or off. In the event of a short circuit, the contact bridges are to be opened rapidly electrodynamically independently of the actuating mechanism. [0003] When the contact bridges are opened, a switching arc occurs between the contacts which, at high temperatures, leads to ma...
