METHOD OF ADJUSTING THE SWITCH-GAP IN A REED SWITCH

摘要

A method of adjusting the mutual separation (g) of the two overlapping metallic cantilever members (9, 11) within the vitreous envelope of a reed switch, whereby a beam (21) of radiant energy to which the envelope is substantially transparent is directed for a controlled period of time through the envelope onto a localised area (p) of at least one of the members (11), thereby effecting permanent thermally-induced bending of that member (11) about the irradiated area (p).
