PROBLEM TO BE SOLVED: To dispense with three direction mold die-cutting without reduction of the optical axis display visible directions so as to lower the cost of a molding die and so as to diagonally visualize the optical axis display by chamfering the case corner part of a plane facing a mounting face of a case for a switch and projectingly forming an optical axis display part in the chamfered slant part. SOLUTION: Corner parts of a case 1 are chamfered slantingly, and in these chamfered slants, optical axis display parts 6e, 6g are projectingly formed so as not to protrude from the outer dimension of the case 1. In this way, the optical axis display parts 6e, 6f arranged on the upper face of the case 1 are projectingly formed in the slants formed by chamfering the upper face corner parts of the case 1, so that a mold die-cutting in three directions can be used for molding the case 1. Consequently, use of a mold die-cutting in six directions is not required, so that three of the mold die-cutting directions can be omitted and a cost can be lowered.
