ABSTRACT:
A hydraulic switch body (1) has a metal plate (10) and a resin main portion (20) molded on a first surface (13) of the metal plate (10). A hydraulic switch (2) and busbar circuits (30) are mounted in recesses (21) of the main portion (20). Grooves (22) connect the recesses (21) and the outer peripheral edge of the main portion (20) to release a tensile stress created at the outer surface (14) of the main portion (20) due to a difference between shrinkage ratios of resin and metal during the resin molding to prevent the hydraulic switch body (1) from warping. The lengths of the grooves (22) are shortened by using the recess portions (21). Therefore, the grooves (22) are less likely to hinder the arrangement of other structural parts.
