Embodiment Construction

[0013] A switching device according to an embodiment of the invention comprises a control device module according to Fig. 1 and a pole unit module (not shown) connected thereto. Mounted in the frame part 2 of the control module is a working shaft 3 , which is rotatable and suitable for turning the working shaft, and a control shaft 3 for changing the position of the poles of the switching device. The shaft element 6 in the control unit module forms part of the working shaft 3 of the switching unit. figure 2 The control shaft 4 is shown extending generally through the frame 2 of the control device module and is also accessible from the bottom of the frame 2 of the control device module.

[0014] Figure 3a The shaft 6 is shown separated from the control device module of FIG. 1 . The shaft member 6 comprises a first end 10, a second end 12, and two crossheads 14 interconnecting said first and second ends. There is a gap between the crossheads 14 and said gap passes through th...

Abstract

A switching device comprising a working shaft (3) mounted in a frame part (2) and a control shaft (4), the control shaft being rotatable and adapted to turn the working shaft, the working shaft (3) being adapted to Change the pole position of the switching device. One of the two shafts (3, 4) (4) passes through the other shaft (3).

Description

Background technique [0001] The invention relates to a switching device according to the preamble of claim 1 . [0002] A switching device is a device used to open and close an electrical circuit. Switching means generally comprise at least one pole and control means arranged to switch said pole on and off. Switching devices include, for example, switches and switch fuses. [0003] A known type of switching device comprises a control shaft and a working shaft mounted in a frame part, said control shaft being rotatable and adapted to turn the working shaft, which in turn is adapted to change the position of the poles of the switching device. The control axis of such switching devices is generally generally transverse to the working axis. [0004] A problem with the above arrangement is that limiter means have to be provided in the frame part of the switching device for limiting the angle of rotation of the control shaft and / or the working shaft.
