Push switch and push switch system

A push switch comprising:

• a movable contact member that is deformable and has a spring characteristic;
• and
• a first fixed contact member that includes a first fixed contact configured to be contacted with and separated from the movable contact member;
• wherein the push switch is in a contact state in a first position where the movable contact member contacts the first fixed contact in response to the movable contact member being pressed by a pressing operation, and the movable contact member is configured to be further pressed to a second position, and
• wherein the push switch is switched to an on state in response to transitioning from an off state to the contact state, and is switched from the on state to the off state in response to the contact state being released.

A push switch system comprising:

• a push switch;
• and
• a controller configured to determine whether the push switch is in an on state or in an off state,
• wherein the push switch includes
• a movable contact member that is deformable and has a spring characteristic;
• a first fixed contact member that includes a first fixed contact configured to be contacted with and separated from the movable contact member;
• and
• a second fixed contact member that includes a second fixed contact configured to be contacted with and separated from the movable contact member,
• wherein the push switch is in a first contact state in a first contact position where the movable contact member contacts the first fixed contact in response to the movable contact member being pressed by a pressing operation, and the push switch is in a second contact state in a second contact position where the movable contact member contacts the second fixed contact in response to the movable contact member being further pressed by the pressing operation, and
• wherein the controller does not determine that the push switch is switched to the on state in response to a transition from the off state to the first contact state, and determines that the push switch is switched to the on state in response to a further transition to the second contact state, and the controller does not determine that the push switch is switched from the on state to the off state in response to the second contact state being released, and determines that the push switch is switched from the on state to the off state in response to the first contact state being further released.
