Abstract

A microswitch, comprising: a casing consisting of a base casing half (2) and a cover casing half (1); a plurality of terminal pieces (6, 8, 10) received, at their intermediate parts, in slots (4) provided in the base casing half and extending substantially perpendicularly from a surface opposing a corresponding surface of the cover casing half; a contact mechanism accommodated in a cavity (14) in the casing and electrically connected to the terminal pieces; and a push-button member (26) elastically supported by a spring member (16) and projecting out of the casing for actuating the contact mechanism by movement of the push-button member; the terminal pieces being provided with projections extending from their leading edges, and the slot being provided with a recess for receiving the projection; wherein the slot comprises an external part and an internal part which is narrower than the external part, and a projecting length of the projection is larger than a depth of the internal part. Thereby, the projection may be easily fitted into the recess because the terminal piece is still in the broader part of the slot and can be easily shifted at this stage, but, once the projection is received in the recess, the terminal piece is securely held in position by the narrower part of the slot.
