PROBLEM TO BE SOLVED: To provide a wiring fixture in which an electric circuit of a comparatively large current flows can be controlled, and in which problems such as heat generation from a current detective element can be evaded effectively without changing the size of a switch itself. SOLUTION: This is the wiring fixture formed by using an electronic circuit including an electronic part which is arranged on a substrate 50 and which has heat generation property, and in the electronic circuit (1) the substrate constituting the rectifying block is a ceramic substrate or (2), on the rear side of the face of the substrate at which the electronic part is installed, a heat radiation plate formed with materials having thermal conductivity equal to or higher than that of the substrate is installed in a contacted state.
