Abstract

A seesaw switch including a rigid member bridging first and second elastic click members, each elastic click member carrying a moveable contact positioned over a fixed contact. A lever is pivotably positioned over the rigid member and includes a first projection contacting the rigid member near the first elastic click member, and a second projection contacting the rigid member near the second elastic click member. When the lever is pivoted a first angular amount in a clockwise direction, the first projection presses against the rigid member, causing the rigid member to rotate with respect to the second elastic member to buckle the first elastic click member. Further pivoting of the lever in the clockwise direction causes the rigid member to rotate with respect to the buckled first elastic click member, thereby buckling the second elastic click member. Similarly, when the lever is pivoted a first amount in the counterclockwise direction, the second elastic click member is buckled, and further pivoting of the lever subsequently causes the first elastic click member to buckle.
