| Push button support structure for push switch |
|
A push button support structure for a push switch is provided with a housing, a push switch secured to the housing which has an actuator thereon, and a push button reciprocally moveable between on and off positions so as to responsively engage the actuator and thereby perform on and off switching actions, respectively. A pair of first elongate engagement posts is provided on one of the push button or housing which defines a circular cross-sectional geometry. Each elongate engagement post is positioned on a respective side of the push switch so that the push switch is disposed between the pair of first elongate engagement posts. A pair of second elongate engagement posts, in alignment with the pair of first elongate engagement posts, is also provided on the other of the push button or housing and defines a square cross-sectional geometry. Respective ones of the first and second pairs of elongate engagement posts are coaxially mated with one another for relative slidable movement therebetween, and are sized and configured so as to establish orthogonally oriented pairs of diametrically opposed linear contact regions therebetween. As a result, frictional resistance is minimized during reciprocal movement of the push button.
