Pressing mechanism of push switch and push switch

A pressing mechanism of a push switch comprising:

• an operation member configured to be pressed;
• and
• a movable contact point member in a leaf spring form that includes a dome portion bulging in a dome shape and an opening portion provided in a central portion of the dome portion, the movable contact point member generating a tactile sensation on the operation member by an inverting operation of the dome portion in response to being pressed by the operation member,
• wherein the pressing mechanism is implemented on a substrate including a first fixed contact point member and a second fixed contact point member, and while the movable contact point member is not pressed by the operation member, the movable contact point member is in contact with the second fixed contact point member, and
• wherein the operation member includes
• a first pressing portion configured to press the first fixed contact point member or the substrate through the opening portion and
• a second pressing portion configured to press the dome portion against the first fixed contact point member.
