Turn signal switch

A turn signal switch comprising:

• an operation lever that can be operated to swing along a first operation direction, operated in a pushing operation direction, and operated in a second operation direction that is linear and different from both the first operation direction and the pushing operation direction;
• and
• a contact part that switches between a conduction state and a non-conduction state in accordance with whether the operation lever is operated to swing along the first operation direction, operated in the pushing operation direction, or operated in the second operation direction,
• wherein:
• the operation lever is configured to, after one end of the operation lever is operated to swing along the first operation direction or operated in the pushing operation direction, be returned to a neutral position at which the operation lever is held when not operated and, when the one end of the operation lever is operated in the second operation direction, be held at a position at time of the operation;
• the operation lever has a sliding member provided at other end of the operation lever, and a biasing member that biases the sliding member in the pushing operation direction;
• a member to slide on is included on which the sliding member can slide;
• the member to slide on, which the sliding member abuts against, has a valley part provided along the second operation direction and an inclined surface extending in the first operation direction with the valley part as a boundary;
• the valley part has a convex part protruding toward the operation lever;
• the convex part is formed in a manner that the sliding member can climb over when the operation lever is operated along the second operation direction;
• a distance from a position at which the sliding member abuts against the inclined surface to the valley part when the operation lever is operated to maximally swing in the first operation direction is more than a distance from a maximum protruding part of the convex part to the valley part;
• the inclined surface is fractionated into a first inclined surface and a second inclined surface with the convex part as a boundary in the second operation direction;
• the first inclined surface is a surface on which the sliding member slides when the operation lever is operated in the first operation direction;
• and
• the second inclined surface is provided in a manner that a height of the second inclined surface gradually increases with increasing distance from the first inclined surface in the second operation direction.

• a distance from a position at which the sliding member abuts against the inclined surface to the valley part when the operation lever is operated to maximally swing in the first operation direction is more than a distance from a maximum protruding part of the convex part to the valley part;
• a transform mechanism that transforms the operation in the second operation direction to an input in the pushing direction;
• the contact part has a first contact part that becomes conductive when the operation lever is operated in the first operation direction, and a second contact part that becomes conductive when the operation lever is operated in the second operation direction;
• and
• the first contact part and the second contact part are placed on a same board.
