Abstract: A low-voltage switching device including a plurality of arc-extinguishing chambers, wherein each of the arc-extinguishing chambers encloses a contacting unit including a stationary contact and a movable contact and arcs are formed when the movable contact is disconnected to the stationary contact, each of the arc-extinguishing chamber including a plurality of U-shaped arc extinguishing plates arranged for splitting, guiding and cooling the arc formed between the contacts and sidewalls provided with guiding means for guiding the arms of the arc extinguishing plates. The guiding means includes a plurality of supporting plates and the supporting plates are arranged protruding towards interior of the arc-extinguishing chamber for receiving the arms of the arc-extinguishing plates and for providing electrical isolation between arms of two adjacent arc extinguishing plates.

Abstract: An electrical circuit switch including: a first movable element configured for being movable by a force applied to the first movable element, the force having a direction parallel to a first axis; and a second movable element including a movable contact and being configured for, by means of the force, moving the movable contact in parallel to a second axis between an open and a closed position, corresponding to the switch opening or closing an electrical circuit. The first axis forms an angle to the second axis and the first movable element and the second movable element are pivotally arranged to each other in a first joint.

Abstract: A noise reducing joist system includes a joist hanger, a joist and a sheath surrounding a bottom portion, a lower end portion and lower end side portions of the joist, the sheath and joist inserted into the joist hanger. The joist and sheath are inserted into the joist hanger. The sheath interfaces with the joist hanger rather than the joist thereby reducing noise that may be created by a sliding that might occur between the joist end the joist hanger.
