TRIGGER SWITCH

PROBLEM TO BE SOLVED: To provide a trigger switch for which the waterproof around a rotation detection part having a first conductive member for connection, connected to the rotation detection part, is improved.SOLUTION: A trigger switch comprises: a trigger switch unit 3 comprising: a rotation axis 5 having an outer case 4, a first operation part 1 and a unit case 11 housed in the outer case 4 and having a waterproof structure, and formed in the unit case 11; a rotation detection part 8 housed in the unit case 11 and for detecting the rotation operation of the rotation axis 5; and a male type connector 7 having a plurality of output terminals 7a exposed to outside and when combining with a female type connector, having a waterproof structure; and converting means 6 for converting a reciprocating movement of the first operation part 1 into a rotational movement to rotate and drive the rotation axis 5. A plurality of first conductive members 9 for connection electrically connecting the rotation detection part 8 and output terminals 7a, are arranged inside of the unit case 11.
