1. A lever switch comprising:
a case;
a click feeling generator disposed inside the case; and
a switch moving body that is disposed inside the click feeling generator and turns with respect to the case about a turn fulcrum in response to an operation of an operation lever, wherein
the click feeling generator includes a clicking surface that abuts with an end portion of the switch moving body and generates a click feeling by causing a reaction force against the operation of the operation lever,
a region of the clicking surface, being from a first position to a second position, forms a shape of a convex curved face being convex toward the turn fulcrum, where the first position and the second position are a position where the reaction force starts to decrease from a peak and a position where the reaction force becomes zero, respectively, in a stroke in which the switch moving body turns from a first angle formed by the click feeling generator with the switch moving body to a second angle formed by the click feeling generator with the switch moving body and being different from the first angle, and
a radius of curvature of the region is not constant and is a maximum at a first portion adjoining the first position in the region.
