A protection device includes a movable arm, a fixed terminal, and a bimetallic member, and a casing that accommodates them, the bimetallic member is located either above or below the movable arm, one end of the bimetallic member applies force to one end of the movable arm, thereby holding one end of the movable arm and the fixed terminal in contact.

A temperature-dependent switch comprises a first stationary contact, a second stationary contact, and a temperature-dependent switching mechanism having a movable contact member. In its first switching position, the switching mechanism presses the contact member against the first contact and thereby produces an electrically conductive connection between the two contacts. In its second switching position, the switching mechanism keeps the contact member spaced apart from the first contact. The temperature-dependent switching mechanism further comprises first and second temperature-dependent snap-action parts which switch from geometric low-temperature configurations to geometric high-temperature configurations when exceeding first and second switching temperatures, respectively, and switch back when subsequently falling below first and second reset temperatures, respectively. Switching the first and/or the second snap-action part from its geometric low-temperature configuration to its geometric high-temperature configuration brings the switching mechanism from its first switching position to its second switching position.

A thermal protector includes, in a fixed manner, a first terminal and a second terminal that are respectively connected to external circuits, at lower left/right ends of the longitudinal directions of a base, and a right end at which a movable plate and a bimetal are superimposed is fixed to the right end of the upper surface of the base and is connected to the second terminal. A fixed contact is fixed to an internal end of the first terminal that is exposed in the left end of the base. A movable contact is fixed at a position facing the fixed contact on the lower surface of the left end of the movable plate. A partition wall that encloses the movable contact and the fixed contact from three directions is provided and bent plate planes are formed on both sides of the movable plate in the vicinity of the movable contact. The bent plate planes adjust the flow direction of hot air in cooperation with the partition wall so as to prevent a malfunction of a breaking arc flying to surrounding conductive members.

A temperature switch includes an elastically deformable movable plate, a movable contact on the movable plate, a fixed contact facing the movable contact, a thermally deformable member, a vibration suppression section, and a cover. The thermally deformable member is elastically deformed in accordance with a temperature change to elastically deform the movable plate such that the movable contact is in contact with the fixed contact or spaced apart from the fixed contact. The vibration suppression section suppresses vibrations of the movable plate by contacting a fixed-edge side when the movable plate is elastically deformed to shift the movable plate from being in contact with the fixed contact to being spaced apart therefrom. The cover surrounds the movable and fixed contacts, and the vibration suppression section is a projecting section provided on the cover.
