PROBLEM TO BE SOLVED: To make a substrate layout free from restrictions, prevent accidents such as short-circuiting, and make a fixing work easy, in surely fixing a switch substrate to a switch case without looseness. SOLUTION: An insertion-coupling projection 12 is provided at a side end part facing to a switch substrate 1, an insertion-coupling hole 22 corresponding to the insertion-coupling projection 12 as well as a support pin insertion hole 23 are provided at a side wall 21 facing to a switch case 2. The insertion-coupling projection 12 is inserted into the insertion-coupling hole 22, a support pin 3 is inserted into the support pin insertion hole 23, and the switch substrate 1 is pressed onto the insertion-coupling hole 22 with the support pin 3 to fix the switch substrate 1 to the switch case 2.
