(57) 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.
