Abstract
A dome sheet for a panel switch includes a planar and resilient metal sheet (1), a number of domes (2) punched from the metal sheet, and a number of positioning members (3) made of insulative material for positioning the domes with the metal sheet. A manufacturing process for the dome sheet includes steps of processing a metal sheet to form a number of original domes (22) partially separate from the metal sheet, applying a plurality of positioning members to fix the original dome to the metal sheet, and electrically isolating the original dome from the metal sheet.

A dome sheet for a panel switch comprising:
- a planar and resilient metal sheet;
- a plurality of domes separated from the metal sheet;
- and
- a plurality of positioning members made of insulative material for connecting the plurality of domes with the metal sheet.
A method for manufacturing a dome sheet comprising steps of:
- processing a metal sheet to form a plurality of original domes partially separate from the metal sheet;
- applying a plurality of positioning members to fix the original dome to the metal sheet;
- and
- electrically isolating the original dome from the metal sheet.
A dome sheet for a panel switch comprising:
- a planar metal sheet defining a plurality of openings therein;
- a plurality of domes disposed in the corresponding openings, respectively, without radially touching the metal sheet so as to form an annular space between each of said domes and the metal sheet;
- and
- a plurality of dielectric linking members disposed in the opening to link the domes with the metal sheet so as to allow the domes up and down moveable relative to the sheet.
