A switch device with an erroneous operation preventer, including: a switch main body (20) having a switch member (22) supported by a shaft (24) with respect to a casing (21) and configured such that pushing a first end portion (25) of the switch member causes a second end portion (26) thereof to protrude and such that an on state and an off state of the switch main body are changed by pushing one of the first and second end portions; and a frame-shaped erroneous operation preventer (30) disposed around the switch member for preventing an erroneous operation on the first end portion that takes a protruding posture when the switch main body is in one of the on and off states, the preventer having side protective walls (31) extending in a longitudinal direction of the switch member so as to cover a surface of a flange portion (21a) of the casing on both sides of the first end portion.
