A slide button is slidably mounted on a case, and a push button having a cylindrical shaft portion is provided in a hole of the case so as to be moved in a direction perpendicular to the sliding direction of the slide button. The push button is pushed by sliding the slide button so as to close a switch. An O-ring is disposed between the cylindrical shaft portion of the push button and an inside wall of the hole of the case.
