PROBLEM TO BE SOLVED: To improve the assembling workability and to secure a high contact reliability, by providing plural constant contacts and an operation time contact to an E-shape operation side contact. SOLUTION: The constant contacts 2 of an E-shape operation side contact 1 are contacted to the fixing side contacts 4 provided at the opposite positions in the E-shape operation side contact 1 constantly. And when a push-button switch is operated, a button 5 for operating side contact operation is operated, and the E-shape operation side contact 1 is deflected. As a result, the operation time contact 3 of the E-shape operation side contact 1 is contacted with the fixing side contacts 4, so as to form the inner circuit of the push-button switch. Since the E-shape operation side contact 1 has plural constant contacts 2 and the operation time contact 3, a high contact reliability can be secured. And since the contact interval between the E-shape operation side contact 1 and the fixing side contacts 4 is determined only by the manufacturing accuracy of the E-shape operation side contact 1, the adjustment or the like of the contact interval are made unnecessary, and the assembling workability can be improved. |
