<p>The invention relates to a wafer switch equipped with a preselector for achieving a continuous switch between the plugs on the winding of a wafer switch. The wafer switch equipped with a preselector, in which the preselector conceived as a subassembly distinct from the wafer switch subassembly is mounted in a separate housing (1 and 23) made of insulating material, in which there is located a switching rod (5 and 27), and some fixed preselecting contacts (2, 3, 4; 24, 25 and 26) have an annular form and are located inside this housing (1 and 23) of insulating material in distinct planes and insuch a way as to surround the switching rod (5 and 27), and on each of the preselecting contact bridges (6 and 28) there are mounted contact parts (8, 9, 10, 11; 17, 18, 30 and 31) resiliently resting in the radial direction, so that when passing in front of one of the preselecting contacts (2, 3, 4, 24, 25 and 26, they may be pushed inwards in a direction contrary to the force exerted by the springs.</p> |
