Abstract: An electrical circuit, comprising:at least one conductive pressing, inset moulded in an insulating plastics support, the pressing(s) providing an electrical circuit on which is mounted at least one surface mounted electronic component, and connector terminals to provide electrical power to the circuit and one or more electrical inputs to and/or one or more electrical outputs from the circuit.

Abstract: An electrical rotary switch is disclosed having a rotary operating member (16) mounted for rotation about an axis. A first contact member (32) is mounted for movement in opposed directions along a path transverse to but not intersecting the axis, between a first position in which a contact surface (38) of the first contact member (32) is in electrical contact with a contact surface (42) of a respective second contact member (36) and a second position in which the contact surfaces are not in electrical contact. The path is approximately normal to the contact surfaces, and the operating member has a surface (44) to impart movement to the first contact member in one or both directions.
