Abstract
An arcing chamber assembly is described having two side walls, a contact compression spring, a contact link, a slide which can be mounted one behind the other in the interior of the arcing chamber assembly, just by stacking them from one side. For this purpose, the arcing chamber assembly includes a passage, whose length is at least equal to the length of the contact link on the component supply side.
Claims9
A switching device, comprising:
- an arcing chamber assembly having two opposite side walls, the two opposite side walls forming an internal area;
- a moveable slide mounted in the internal area for motion, when in operation, along an axis;
- a contact compression spring disposed in the internal area for compression along the axis of motion of the slide;
- a moving contact link associated with fixed contacts, the contact link being held in an opening in the slide using the contact compression spring, the contact link being fed through a passage from above along the axis of motion of the slide into the internal area so that the contact link is held between the compression spring and the slide, the passage extending from the internal area between the two opposite walls to an exterior and having a length at least equal to a length of the contact link.
