ABSTRACT:
A proximity switch or contactless switch circuit comprises within a casing a flexible insulating carrier provided along a component side with a multiplicity of electronic components connected by conductive strips to form the contactless or proximity switch circuit. An extension of the carrier or the opposite side of the carrier are provided with continuous conductive coatings so that when the carrier is folded or rolled within the casing, a portion of the carrier strip provided with the coating or layer forms an additional shield.
