Abstract
A push switch includes a movable contact including a dome part that is shaped like a dome and configured to be inverted in shape when pressed, and a fixed contact including a first fixed contact, the movable contact being configured to be brought into contact with and away from the first fixed contact. The push switch is configured such that an operating load necessary to press the movable contact gradually increases after the movable contact starts to be pressed, decreases thereafter when the dome part is inverted, and increases again when the movable contact is further pressed, and the dome part contacts the first fixed contact after an inflection point at which the decreased operating load starts to increase again.
