PROBLEM TO BE SOLVED: To make easy to attach a contact spring plate to a housing case. SOLUTION: In a bidirectional lever switch 1, a control lever 6 provided in the housing 2 turns in an arc from a center line L to the right or to the left within a predetermined angle so that a movable contact moving together with the control lever 6 gets or loses contact with a fixed contact 4 which consists of a common fixed contact 41 attached to the housing 2, and left and right fixed contacts 42 and 43, respectively. The movable contact is composed of a contact spring plate 5 in which an attached strip 51, having a common contact 54 which is always in contact with the common fixed contact 41, and left and right spring strips 52 and 53, having left and right movable contacts 55 and 56, respectively, which get or lose contact with the left and right fixed contacts 42 and 43, respectively, are integrated. In the attaching structure of the contact spring plate 5 to the housing case 2, a boss 26 formed in the center of the inside of the housing case 2 is put through a through-hole 58 opening in the center of the attached strip 51 to be fastened and a projection 27 formed in the housing case 2 is fixed into a groove 59 cut into the attached strip 51 to stop rotation.
