Abstract: A mechanical switch in a laptop computer or other electronic equipment is surrounded by a protective, electrostatically shielding bellow-shaped housing that is formed from a nickel metal. Preferably formed by casting, the bellows has a sidewall thickness of about 0.06 mm to about 0.12 mm, a diameter ranging from about 2.6 mm to about 10 mm, and a compressive actuation displacement ranging from about 2 mm to about 8 mm.

Abstract: A spring charging mechanism for electrical circuit breakers and transfer switches of the type in which a spring is charged by rotation of a shaft. The charging mechanism has a charging shaft with two independently operating ratchet mechanisms coupled thereto.

It also features an inexpensive and easily-installed flexible, resilient, insulating sleeve which insulates the charging mechanism from the operator, and a key arrangement for coupling a handle to a ratchet mechanism which distributes stress within the handle and protects the handle fastening screws from destructive shear stresses.

Abstract: A switching device for super high frequency ranges comprising a common fixed contact and a pair of selectable fixed contacts, and moveble contacts which are slidable over them so as to selectively and electrically connect the common fixed contact to one of the selectable fixed contacts. A pair of buffer electrodes are placed between the common fixed contact and the selectable fixed contacts to reduce the electrostatic capacitance between the fixed contacts and reduce signal attenuation in super high frequency ranges. The buffer electrodes are electrically isolated without being connected to any external circuit and thereby reduce electrical capacitance produced between the common fixed contact and the selectable fixed contacts without creating excessive gaps therebetween. Such gaps would prevent smooth sliding movement of the moveable contacts.

Abstract: A moulded case low voltage circuit breaker for high currents has no arcing contacts and is equipped with arc blow-out means drawing the arc very quickly away from the contacts. An insulating shield associated with the moving contact forms an arc formation chamber of a small volume which is open in the direction of the arc chute. The moving and stationary contacts are fitted with arcing horns constituting a small divergent path in proximity to the contacts favoring rapid displacement of the arc, this divergent path leading to an area defined by a hump of the horn. In this area, the clearance of the arcing horns is smaller than the clearance between the contacts as soon as the latter separate to avoid any rearcing on these contacts.
