PROBLEM TO BE SOLVED: To give slant thrust operation to a thrust operation portion of an operation member without causing impact noises when cancelling the thrust operation. SOLUTION: A protruded portion 13 of a mover 12 movably provided in point or line contact with the interior of a case 11 through the protruded portion 13 is placed opposite to or almost opposite to a contact portion 14a of a movable contact 14 with a fixed contact 16 in the direction perpendicular to the moving direction of the mover 12. When slant thrust operation, as shown by arrowmarks B, C, is given to a thrust operation portion 17a of an operation member 17, the angle of the partial pressure of contact pressure P of the movable contact 14 on the fixed contact 16 is nearly 90 degrees and torque on the mover 12 and the operation member 17 is almost zero. Therefore, the operation, if cancelled, eliminates the possibility of collision of the mover 12 and the operation member 17 with the case 11.
