PROBLEM TO BE SOLVED: To provide mat switch equipment which demonstrates high reliability over a long period of time, while an incorrect operation is hard to occur regardless of a using environment and an action direction of pressure. SOLUTION: A softly elastic insulator 1, which is formed so that two or more penetrating hole 1a, which have openings to both the front and back sides, may be distributed on a plate face, a pair of electric conductors 2a and 2b distributed on both the front and back sides of the softly elastic insulator 1, and two or more conductive roller 3 a, which are shut up in non-contacting state with at least one of the conductors as to be possible to roll in the spaces separated by each the penetrating holes 1a of the softly elastic insulator 1 and a pair of electric conductors 2a and 2b, are provided. According to a request, a stabilizing plate can be arranged on the external surface of the electric conductor, at least one of the conductors can be divided into two or more elements, which are insulated each other, a compression regulating pipe body of the softly elastic insulator can be arranged inside the penetrating hole, and an assembled body of the softly elastic insulator 1, the pair of the electric conductors 2a and 2b, and the conductive roller 3, can be contained in a moisture preventing or a dust protecting bag, or a rubber mat 7.
