Embodiment Construction

[0023] Electrical switches typically contain several switch modules / poles, which are stacked together to form a multi-pole switch. Each module may include an insulating housing housing the electrical components of the switch module. Each module housing may comprise a first housing half and a second housing half made of plastic, eg assembled together to form a switch module. The housing modules may be generally rectangular.

[0024] figure 1 An embodiment of an electrical switch module is shown showing a first housing 102 equipped with components of the module. The second housing of the switch module to be assembled against the first housing 102 for forming the module and covering the switch members is not shown.

[0025] figure 1 Two stationary contacts 110, 112 are shown at opposite ends of the module and a movable contact 130 to move between the open and closed positions of the switch. In order to perform the rotary motion of the movable contact 130 , the device compris...

Abstract

A contact arrangement of an electric switch, comprising a first stationary contact (110), a second stationary contact (112) and a movable contact (130) for making an electrical connection between the first (110) and second (112) stationary contacts, wherein the movable contact (130) is pivotally connected to the first stationary contact (110) by a pivotal connection for allowing the movable contact (130) to pivot with respect to the first stationary contact (110) about a pivoting axis (116, 135) such that in an open position of the switch, the movable contact (130) is disconnected from the second stationary contact (112), and in a closed position of the switch, the movable contact (130) is in contact with the second stationary contact (112). The movable contact (130) and the first stationary contact (110) are arranged in a first angle with respect to each other in the open position of the switch, and in a second angle with respect to each other in the closed position of the switch, and the second angle is greater than the first angle.

Description

technical field [0001] The invention relates to a current switching device. Background technique [0002] A number of issues affect the design of current switching devices. Design goals include, for example, ease of assembly of the switch, possibility of assembling various switch types, safety in use of the switch, quick connection and disconnection of the contacts and efficient extinguishing of the arc when the contacts separate. Contents of the invention [0003] It is an object of the invention to provide an improved current switch. This object is achieved with the invention defined in the independent claims. Some embodiments are disclosed in the dependent claims. Description of drawings [0004] The present invention is described in more detail by some embodiments below with reference to accompanying drawing, wherein: [0005] figure 1 An embodiment of a switch module is shown; [0006] figure 2 Another view of the switch module is shown; [0007] image 3 ...
