The switch comprises a rigid arm (1) rocking about a transverse shaft (2) mounted on a rigid sole plate (3) and facing a pair of superposed slabs (4, 5). The rocker arm (1) carries a moving optical fiber end (9) which is attached thereto by means of a capillary tube (9). Each of the two slabs (4 and 5) carries a respective platelet (10, 11) having an alignment groove (12, 13) formed therein with a fixed optical fiber end (14, 15) being disposed in each groove. The slabs are temporarily fixed to the sole plate by bolts passing through holes that leave adequate clearance for enabling the positions of the slabs to be individually adjusted relative to the sole plate (3) prior to the slabs being finally fixed by laser spot-welding.
