Claims

[Scope of utility model registration request]

The switch has twin contacts that can be switched by snapping, and includes a housing, a pair of movable contact pieces each having one end separated into two and each having a movable contact attached thereto, and the movable contact piece and the other end. a movable piece having a band-shaped return spring portion whose one end is swingably attached to the left and right center portions between the movable pieces and whose other end is fixed to the housing; and two movable pieces corresponding to the movable contacts. A terminal is provided with a fixed contact and is attached to the housing, and one end has two terminals corresponding to the pair of movable contact pieces.
and the other end is integrated, and the one end is swingably engaged with each tip of the pair of movable contact pieces, and the other end is swung at the swinging tip of the return spring section. 1. A switch comprising: a freely engaged reversing spring for switching a snap; and a push button for pressing down the return spring section from the outside.
