Abstract: The invention describes a switch, preferably a steering column switch, provided with an actuating member moved across the contact sections rigidly connected to the housing in a substantially pushing way. It is the object of the invention to provide a steering column switch which, being of a small-sized design, permanently provides for good contact making between the contacts to be interconnected.

Abstract: A slide switch that can remove foreign particles, such as metallic dust, from its ground terminals. When the movable contact slides toward a stroke end, the power source contact first passes through an end section of the power source terminal before disengaging the terminal. At that instant, arcs are generated between the contact and the terminal. Arcs produce metallic dust, carbide particles, etc. that adhere to the insulator and terminals creating buildup and obstructing the sliding path of the contacts. The switch is provided with a discharge hole and arc gaps along the sliding path of the contacts to eliminate the arc buildup. The contacts carry the metallic dust and carbide particles while sliding so that the dust and particles drop into the discharge hole or arc gap.

Abstract: A frame component for a notebook computer wherein the frame component has tapered (e.g., conical) depressions that receive protrusions from printed circuit boards mounted adjacent the frame component. The tapered depressions are formed during plastic injection molding of the frame component by a tapered (e.g., conical) protrusion in the interior cavity of the mold.

This results in an overall reduction in the thickness of the frame component from on the order of 3-4 mm to on the order of 1.5 mm. The tolerance between the bottom of the depression configured to receive the protrusion from the printed circuit board is on the order of 0.3-0.4 mm.
