In a switching circuit, at least two bus bars are fixed with an insulator interposed therebetween and secured to a substrate of the switching circuit. Being combined with the bus bars, the insulator serves not only to insulate those bus bars but also to enhance the bending rigidity and bending strength of the switching circuit. As current flows in one of the bus bars in a direction opposite to a direction in which current flows in the other bus bar, the inductance of the bus bars is reduced, resulting in the decreased fly-back voltage generated upon switching operation.
