A waterproof switch device is for use with an elongated actuator in a water containing chamber, and includes a top cover wall spaced apart from the chamber and having a bore for movement of the actuator in response to a reach of a predetermined water level. A rear wall and two engaging walls are integrally formed with the top cover wall to form an inner major surface. A groove forming wall is integrally formed with and extends from the inner major surface, and is spaced apart from the top cover wall so as to define an inserting groove therebetween. A switch body is mounted on and is spaced apart from the inner major surface, and has an actuated stud to make a switching action when depressed. A lever includes an actuating end disposed between the groove forming wall and the actuated stud, and a force transmitting end disposed under and moved downward by the elongated actuator to cause the actuating end to depress the actuated stud. A front cover includes a front major wall with two engaging edges fitted with the engaging walls, and an intervening wall inserted into the inserting groove and sandwiched between the lower major surface and the groove forming wall, thereby blocking the water dripping or creeping over the bore from falling directly downwards to the inner major surface.
