<p>A pushbutton actuator assembly for operating a switch includes a cylindrical housing (20) having an axial bore (27) therethrough, one end of the housing (20) having an enlargement (21) containing a cup-shaped cavity (23) communicating with the bore (27). An elongated tubular actuator body (31) is reciprocally movable in the bore (27). At one end of the body (31) and received in the cavity (23) is an inverted cup-shaped head (36) having an end wall (37) and a cylindrical side wall (38). The other end of the body is bifurcated to define flexible legs (33). Unitary with the head (36) are three elongated flexible resilient bias members (40) engageable with the bottom of the cavity (23) for resiliently biasing the actuator body (31) to a normal raised rest position.</p> |
