Overlay electrical conductor for a magnetically coupled pushbutton switch
摘要:
A magnetically coupled pushbutton switch has a coupler magnet layer that normally holds an electrically conductive magnetic armature spaced from a substrate layer. An overlay having an overlay electrical conductor formed thereon covers the pushbutton switch. The overlay electrical conductor, which electrically contacts a crown on the armature, is part of a set of electrical conductors that is normally closed. When a user provided actuation force causes the armature to break away from the coupler magnet layer, the set of electrical conductors is opened.
