    Abstract: A push-button switch includes insulating member having a surface, first and second stationary contacts electrically isolated from each other and provided at the surface of the insulating substrate, and a movable contact. The movable contact includes an elastic metal base having a dome-shape and having a concave surface spaced from the first stationary contact and an outer rim mounted on the second stationary contact, a nickel plated layer provided on the concave surface of the elastic metal base and having a thickness ranging from 0.05 μm to 0.5 μm, a copper plated layer provided on the nickel plated layer and having a thickness ranging from 0.05 μm to 0.7 μm, and a silver plated layer provided on the copper plated layer and having a thickness ranging from 0.1 μm to 2 μm. The push-button switch has a long operating life time, has a stable contact resistance, and is inexpensive.

    Abstract: A system includes a mechanical switching device having a first moveable contact operatively connected to selectively contact a first static contact. A second moveable contact is operatively connected to selectively contact a second static contact that is electrically connected in parallel with the first static contact. The first and second moveable contacts are mechanically connected to each other to move between a closed circuit position and an open circuit position. The first moveable contact contacts the first static contact before the second moveable contact contacts the second static contact as the first and second moveable contacts move into the closed circuit position from the open circuit position. The first moveable contact disconnects from the first static contact after the second moveable contact disconnects from the second static contact as the first and second moveable contacts move from the closed circuit position into the open circuit position.

    Abstract: A high-voltage multipolar circuit breaker including a first chamber for receiving gases, in communication with a first arc quenching chamber, and including a first aperture for exhausting gases to the exterior of the casing, the aperture being provided with a first downstream filtering device. The circuit breaker furthermore includes at least one second chamber for receiving gases, in communication with at least one second arc quenching chamber of another pole of the circuit breaker, the chamber itself being equipped with a second upstream device for filtering gases, the second chamber for receiving gases including a second aperture for exhausting gases to the exterior of the casing, the chamber being provided with a second downstream filtering device, the first chamber for receiving gases and the second chamber for receiving gases being separated fluidically one from the other by an impermeable wall.
