Provided is a dome-shaped spring for placing on a substrate having stationary contacts, and a circumferential edge of the dome-shaped spring is continuously in contact with the stationary contacts. At least a part of a neutral plane has a shape defined by an even function of at least eighth-order. Angle α of the neutral plane of the dome-shaped spring to the substrate at a second inflection point that exists at a second-positioned inflection point from the circumferential edge, angle β of the neutral plane to the substrate at a first inflection point, and angle γ of the neutral plane at the circumferential edge of the dome-shaped spring to the substrate satisfy following inequalities of α β and β γ.

Disclosed is a dome shaped spring including: a dome shaped spring section in which buckling occurs by pushing, wherein at least a portion of a neutral face of a movable portion when buckling of the dome shaped spring section occurs is an aspherical shape.

Upper and lower leaf springs linear-movably support a sub movable portion with respect to a sub fixed portion. Each of the upper and lower leaf springs has a substantially symmetrical shape, which is symmetric with respect to a center portion thereof, so as to be mounted on the sub fixed portion at the center portion and so as to be mounted on the sub movable portions at both end portions thereof. Each of the upper and lower leaf springs has at least one pair of bending portions, which is symmetric with respect to the center portion, between the center portion and the both end portions.
