PURPOSE:To make the titled switch easily usable, by mounting a switch lever revolving by the setting provided to a dial rotating at a constant cycle, a switch contact opened and closed by said lever and a manual operation piece freely movable in cooperation with said lever and also used in displaying a contact state. CONSTITUTION:Because a spring member 53 is planned so that the force thereof is weaker than that of a contact spring 59, when a contact mechanism part 60 is turned OFF, a switch lever 55 moves to an A-direction and, therefore, a manual operation piece 50 moves to a B-direction while a knob 51 comes to an OFF-side 52a in a guide slot 52 to shown an OFF-state. In an ON-state, because the lever 55 moves to the direction opposite to the A-direction, the operation piece 50 moves to the direction opposite to the B-direction and the knob 51 comes to an ON-side 52b to show an ON-state. By this method, the ON/OFF states of switch contacts 57, 58 can be visually confirmed. |
