Rotary switch

A rotary switch comprising:

• a housing having a ring-shaped outer wall so that an annular recess is formed;
• a rotor which is rotatably supported on the housing around a center axis of the annular recess;
• a plurality of stationary contacts each having a circular arc shape and provided on a bottom face of the annular recess on a same circle along an inner face of the outer wall of the housing;
• a moving contact which is provided on the rotor and is connected and disconnected with the stationary contacts following to rotation of the rotor with respect to the housing;
• and
• a cable draw-out portion from which an electric cable including a plurality of inner cables respectively connected to at least the stationary terminals is drawn out from the housing, wherein
• the cable draw-out portion has a terminal base on which terminals connected to at least the stationary contacts are held;
• the terminal base and the electric cable are respectively sealed by a sealing material under a condition that core wires of the internal cables are respectively electrically connected to the terminals;
• and
• the terminal base has a flange that restricts an area to which the sealing material flows in sealing process.
