Abstract

The keyboard type tumbler switch has a case (1) with holes (3, 4) for connecting two twin wires (5, 6). It also has three spring strips (29, 30, 31). Two of the strips (29, 30) are located on each side of the third strip (31) and these have switch contacts (29a, 30a) at one end and a hair-pin shape at the other end (29c, 30c). The third strip (31) has both ends with hair-pin shapes. Connections of the wires (5a, 5b, 6a, 6b) are made by clamping the conductors of the wires between the hair-pin shaped ends of the strips and wedge shaped bosses which are part of the case.
