Unitized appliance control panel assembly and components of the assembly
First Claim
1. An appliance control panel assembly, comprising:
- a control panel fascia;
a plurality of push-buttons presented in apertures of said fascia; and
a unitized electronics enclosure assembly mated with a rear side of said control panel fascia, said electronics enclosure assembly including a rear electronics enclosure housing;
a printed circuit board (PCB) contained within said housing, said PCB having electronic control panel components mounted thereon, including at least one switch; and
a front enclosure panel engaged with said housing so as to cover a substantial front side portion of said PCB, said front enclosure panel comprising at least one integrally formed spring member associated with at least one of said plurality of push-buttons and operable to permit said push-button to be pressed against a bias of said spring member to releasably actuate said at least one switch, said integrally formed spring member including a moveable platform engageable with a rearward portion of said push-button, said moveable platform being formed with raised surface portions extending in a closed loop so as to surround, in spaced relation, a contact region of said rearward portion of the push-button with said moveable platform.

Abstract
An electronics enclosure and associated components form a self-contained, unitized assembly including control buttons and illuminated indicator elements, that can be mated as a single piece with an outer user interface control panel fascia. A front panel of the electronics enclosure provides a mounting location for various buttons and lighted indicators that will show through mating apertures provided in the control panel fascia. This may include light pipe collars and integral spring levers. Specially configured cup structures may be integrally molded at the ends of the spring levers to provide electrostatic discharge (ESD) protection. A mount of planar spring button pieces on the front enclosure panel, over the associated spring levers, results in an assembly incorporating two springs serving to bias the associated button to its return position, and eliminating any rattle or looseness of the parts.
