Push operation switch
A switch may include: a movable member comprising a movable piece extending from a swing shaft and being swingable around the swing shaft; and a pressing member configured to press the movable piece while moving in response to a pushing operation, the movable piece swinging in response to pressing from the pressing member. The pressing member comprises a first contact portion configured to slide along an extending direction of the movable piece in a state of being in contact with the movable piece due to movement by the pushing operation, and a second contact portion configured to be in contact with the movable piece at a position different from a position where the first contact portion is in contact, due to the movement by the pushing operation, and the pressing member presses the movable piece by the first contact portion and the second contact portion in a contact state.
1. A switch comprising:
a movable member comprising:
a movable piece extending from a swing shaft and being swingable around the swing shaft; and
a pressing member configured to press the movable piece while moving in response to a pushing operation, the movable piece swinging in response to pressing from the pressing member, wherein
the pressing member comprises
a first contact portion configured to slide along an extending direction of the movable piece in a state of being in contact with the movable piece due to movement by the pushing operation, and
a second contact portion configured to be in contact with the movable piece at a position different from a position where the first contact portion is in contact, due to the movement by the pushing operation, and
the pressing member presses the movable piece by the first contact portion and the second contact portion in a contact state.
2. The switch according to claim 1 , further comprising an energizing member configured to energize the first contact portion in a direction substantially orthogonal to a moving direction of the pressing member,
wherein the first contact portion is energized by the energizing member to press the movable piece in a direction substantially orthogonal to the moving direction of the pressing member, and
the second contact portion presses the movable piece in a direction substantially parallel to the moving direction of the pressing member.
3. The switch according to claim 2 , wherein, in a movement process of the pressing member by the pushing operation, a section in which the first contact portion is in contact with the movable piece is longer than a section in which the second contact portion is in contact with the movable piece.
4. The switch according to claim 3 , further comprising a fixed contact,
wherein the movable member has a movable contact in a vicinity of a tip extending from the swing shaft of the movable piece, and the movable contact is in contact with and separates from the fixed contact by swinging of the movable piece.
5. The switch according to claim 2 , further comprising a fixed contact,
wherein the movable member has a movable contact in a vicinity of a tip extending from the swing shaft of the movable piece, and the movable contact is in contact with and separates from the fixed contact by swinging of the movable piece.
6. The switch according to claim 1 , wherein in a movement process of the pressing member by the pushing operation, a section in which the first contact portion is in contact with the movable piece is longer than a section in which the second contact portion is in contact with the movable piece.
7. The switch according to claim 6 , further comprising a fixed contact,
wherein the movable member has a movable contact in a vicinity of a tip extending from the swing shaft of the movable piece, and the movable contact is in contact with and separates from the fixed contact by swinging of the movable piece.
8. The switch according to claim 1 , further comprising a fixed contact,
wherein the movable member has a movable contact in a vicinity of a tip extending from the swing shaft of the movable piece, and the movable contact is in contact with and separates from the fixed contact by swinging of the movable piece.
