Claims

[Scope of utility model registration request]

(1) First and second terminals each having a terminal protruding from the outside of the case
A movable contact is installed near the free end of the leaf spring member whose base is connected to the terminal and the first terminal, and a fixed contact is installed near the free end of the bimetal whose base is connected to the second terminal, and the leaf spring member The other end of an arcuate spring whose one end is engaged with the free end of the plate spring member and applies a biasing force toward the base of the leaf spring member is locked to the inner wall of the case, and the free end of the leaf spring member that is generated due to the deformation of the bimetal is fixed to the inner wall of the case. At one of the two stable points, the movable and fixed contacts are held in pressure contact, and at the other point, the fixed and movable contacts are separated. On the other hand, an engaging portion inside the case of a presser protruding from inside and outside the case is engaged with the plate spring member, and the plate spring member is stabilized based on the pushing/pulling motion of the presser. A small switch characterized by being able to be set from one point to the other stable point.

(2) The small switch according to claim 1, wherein the direction of deformation of the bimetal due to overcurrent coincides with the direction of pressure contact between the movable and fixed contacts.
