Description
Technical Field
[0001] This utility model relates to the technical field of temperature control, and in particular to the technical field of temperature controllers. Background Technology
[0002] A snap-action thermostat is a bimetallic strip thermostat.

The second fixed contact 25 separates from the second movable contact 26, and the movable rod 6 cuts off the path formed by the second fixed conductive strip 23 and the second movable conductive strip 24. When the temperature returns to below the jump temperature of the first bimetallic strip 43, the first bimetallic strip 43 resets, the movable rod 6 resets, and the second movable conductive strip 24 also resets. The second fixed contact 25 and the second movable contact 26 re-engage, and the second fixed conductive strip 23 and the second movable conductive strip 24 form a new path.
[0024] When the temperature reaches the jump temperature of the second bimetallic strip 44, the second bimetallic strip 44 jumps, bulging downwards. This pushes the movable cylinder 5 downwards, causing the movable cylinder 5 to bend the first movable conductive piece 14 downwards. The first fixed contact 15 separates from the first movable contact 16, and the movable cylinder 5 cuts off the path formed by the first fixed conductive piece 13 and the first movable conductive piece 14. When the temperature returns to below the jump temperature of the second bimetallic strip 44, the second bimetallic strip 44 resets, the movable cylinder 5 also resets, and the first movable conductive piece 14 also resets. The first fixed contact 15 and the first movable contact 16 re-engage, and the first fixed conductive piece 13 and the first movable conductive piece 14 form a path again.
