发明名称 Easily peelable sheet having contact plates and switch device employing the same
摘要 A sheet having contact plates includes a strip-shaped peel sheet that is peeled while being fed for use, a spacer sheet stuck onto the peel sheet via an adhesive layer, an upper face sheet stuck onto an upper face of the spacer sheet via an adhesive layer, and contact plates stuck to the upper face sheet. The peel sheet and the spacer sheet are provided with penetration holes through which the contact plates can penetrate, and coupling grooves by which the adjacent penetration holes are coupled in a direction crossing a feed direction of the peel sheet. The coupling grooves are shifted at one side in the widthwise direction thereof to rear ends in the feed direction of inner circumferences of the adjacent penetration holes so that there are no protrusions protruding in the feed direction from the rear ends of the inner circumferences of the adjacent penetration holes.
