<p>A contact 24 is fitted to an insulator complete 25, and the contact 24 is adapted to rotate in correspondence with the operation of an operation knob. The length of an arm 38 among arm portions 37 to 39 which are provided on the contact 24 is set to be shorter than the other arm portions 37 and 39. As a result, fixed contacts 40a and 41a with which movable contacts 37a and 38a provided at distal ends of the arms 37 and 38 are brought into contact can be arranged at concentric positions, thereby making it possible to increase the number of contacts. In this case, since a relay for a small-current load is connected to the fixed contact 41a, no hindrance is caused even if the contact force of the second movable contact 38a is set to be small by devising the angles between the respective ones of the arm portions 37 to 39. <IMAGE></p> |
