Unitized control panel

DETAILED DESCRIPTION In order to accomplish the foregoing objective, independent switch actuators are formed by etching a perimetric groove on the outside of the cover plate to define each actuator, and by etching a registering, but just slightly inwardly offset, perimetric groove on the inside of the cover plate.
A thin web is thus formed between the adjacent recess walls which provides localized flexibility, all without undue reduction in wall thickness.
A contact pad is formed on the inside of the cover plate that is in the plane of the cover plate itself.
A simple spacer sheet is interposed between the cover plate and the circuit board on which contact segment pairs are formed.
The spacer sheet has holes to expose the contact pad to the corresponding pair of contact segments.
No supplemental conductive pads or the like are required to build up a contactor.
The resulting structure is simple and effective.
