Switch Actuator

      Described is a one-piece actuator attached to an internal
surface of a bezel for transferring a pushing motion between a
button-like portion of the actuator, extending outward through a slot
in the bezel, and a switch plunger held within a device supported
behind the bezel.

      The Figure is an exploded, partially-sectional isometric view
of the interior surface of bezel 10 and an actuator 12, together with
the tip portion of a plunger 14 operating an electrical switch (not
shown) attached as part of a device (not shown) covered by the bezel
10.  Both bezel 10 and actuator 12 are preferably molded as integral
pieces using thermoplastic resins.

      Since bezel 10 includes an outward-extending front face 16,
outwardly adjacent to switch plunger 14, actuator 12 is used to
transfer a manual pushing motion, occurring at the outer surface 16
of a button-like projection 18 extending through a slot 20 in bezel
10, to plunger 14.  Actuator 12 also includes a mounting portion 22,
a flexible leaf spring portion 24, and a contact portion 26, which is
aligned to push directly on plunger 14.  Bezel 10 includes a pair of
inward-extending posts 28, which extend through holes 30 in contact
portion 26 when actuator 12 is assembled to bezel 10.  Actuator 12 is
held in place against adjacent mounting surfaces 32 by heat stak
ing these posts 28.

      While the flexibility of leaf spring portion 24 allows the
inward motion of projection 18 and of...
