Claims

[Scope of utility model registration request]

A movable contact plate is attached to the base frame so that it can freely tilt in a see-saw manner to one side and the other using its longitudinal middle part as a fulcrum, and a fixed contact is attached to the base frame, and the movable contact plate The movable contact provided on the movable contact plate is mounted so as to come into contact with and separate from the movable contact plate, and in the movable contact plate, the movable contact is disposed on one longitudinal side of the movable contact plate, sandwiching the fulcrum,
The base of the spring piece is connected to the other side, and the tip of the spring piece extends beyond the fulcrum to be located on the side of the movable contact. An operating member having a protruding piece for abutting the spring piece is disposed on the frame so as to be movable back and forth in a direction substantially parallel to the longitudinal direction of the movable contact plate, and a positional relationship between the protruding piece and the spring piece is arranged on the frame. is a state in which, when the operating member is in the retracted position, the protruding piece elastically abuts the spring piece on the base side of the movable contact plate at a position corresponding to the fulcrum of the movable contact plate, causing the movable contact plate to tilt to one side. When the operating member is in the forward position, the protruding piece elastically abuts the spring piece on the tip end side of the position corresponding to the fulcrum of the movable contact plate, causing the movable contact plate to tilt to the other side. In a forward/backward switch having the following relationship, the connection state between the movable contact plate and the base of the spring piece is an arc-shaped folded part that is located between the movable contact plate and the spring piece and is integral with both. A forward/backward switch characterized by being connected by a member.
