A reed switch assembly and method of assembling it are disclosed. A preferred embodiment of the reed switch assembly includes an elongate hollow housing having an opening at one end thereof for access to a cavity therein. A reed switch is positioned completely inside the cavity. The first and second connecting leads of the reed switch are bent so that they are each substantially parallel to their respective first and second reeds and so that they lie in planes that are not coplanar with the flat portions of the first and second reeds. The first connecting lead has a length that is long enough so that it extends at least half-way over the reed switch body towards the second connecting lead. A first wire is attached to the first connecting lead at a connection point that is spaced apart from the free end of the first connecting lead a distance equal to at least one-half the total length of the first connecting lead. An ameliorator magnet is mounted on the first connecting lead between the free end and the connection point to create a magnetic circuit between itself and the first and second reeds in order to reduce the magnetic flux density required to close the first and second reeds. A substantially flat, circular, blocking member is positioned inside the cavity between the reed switch body and the housing opening. The blocking member provides support for the reed switch and substantially centers the reed switch in the housing cavity. Fillant is positioned in the cavity at the housing opening for substantially closing the housing opening.

A segmented focusing mirror having a plurality of segments with each segment having a different focal length is made by constructing a plurality of mirrors with each mirror having a different focal length. The plurality of mirrors are sliced or are cut up into a plurality of segments. One or more segments of one mirror are combined with one or more segments of another mirror to form a master mirror. The master mirror has a common focal point with the segments having different focal lengths. A segmented focusing mirror is replicated from this master mirror by forming a mold of this master mirror and replicating therefrom.
