A controller is disclosed. The controller, in which a knob-side circuit board where a control knob of the controller is formed is contact-connected to a main circuit board, comprises: a controller rear panel which has a partition wall at a side to form an accommodating part; the main circuit board which is disposed on the other side of an upper part of the controller rear panel to be fixed on the partition wall and form a main contact on a bottom surface of a tip end portion protruding toward the accommodating part; the knob-side circuit board which is inserted into the accommodating part and forms a knob-side contact on a top surface of the tip end portion corresponding to the main contact; and a repulsing means which is composed of magnets provided to correspond to each other on an inner side of the accommodating part of the controller rear panel and on a bottom side of the knob-side circuit board, and which makes the main contact and the knob-side contact keep in contact with each other by using repulsive forces between the magnets. |
