A LEVER SWITCH INCLUDES A CASE (11,21), AND A STATIONARY CONTACT (13), COMMON CONTACT (14), MOVABLE CONTACT (15,24) AND LEVER (12) WHICH ARE DISPOSED IN THE CASE (11,21). THE MOVABLE CONTACT (15,24) IS MADE UP OF ELASTIC METAL AND INCLUDES A STATIONARY PORTION (15F, 24A), CONTACT PORTION (15H), AND A CURVED PORTION (15A) LOCATED BETWEEN THE STATIONARY PORTION (15F, 24A) AND THE CONTACT PORTION (15H). THE STATIONARY PORTION (15F, 24A) IS CONNECTED TO THE COMMON CONTACT (14). THE MOVABLE CONTACT (15,24) IS DISPOSED IN A STATE OF BENDING SO THAT THE CONTACT PORTION (15H) MAY COME IN CONTACT WITH OR APART FROM THE STATIONARY CONTACT (13). AN OPERATING PORTION (12C) IS PROTRUDED FROM AN OPENING, AND A DRIVING PORTION (12B) IS LOCATED INSIDE THE CASE (11,21) AND ABUTS ON THE CURVED PORTION (15A) OF THE MOVABLE CONTACT (15,24). WHEN THE OPERATING PORTION (12C) IS MANIPULATED, THE DRIVING PORTION (12B) PUSHES THE CURVED PORTION (15A), AND THEN THE CONTACT PORTION (I5H) COMES IN CONTACT WITH OR APART FROM THE STATIONARY CONTACT (13).
