A movable contact element 15 made of an elastic metal, formed into an approximately reverse isosceles triangle having an elastic contact point 15E, 15F provided at the tip end of two respective elastic feet 15C, 15D extended from the equilateral sides to be crossing downward is placed in the case. An actuating body 16 of approximately isosceles triangle shape is disposed on the top of the movable contact element 15 so as protrusions 16C, 16D provided at the bottom corners press the upper surface of the flexed portions 15A, 15B, respectively, locating at the upper corners of the movable contact element 15. The operation lever 16E of actuating body 16 operates smoothly responding to the forces exerted from the three directions, both the right and the left, as well as from the up.
