Abstract

The invention belongs to the temperature control technical field, which solves the problem that the on-off between contacts is gradual in the prior art, and caused to burn during connection and separation. A temperature adjusting switch is provided, wherein a shell 1 is provided with an elastic sheet 4 and a heat sensitive bimetal strip 5 is arranged on the springy end of the elastic sheet 4. An electric heater 6 is arranged on the heat sensitive bimetal strip 5, wherein the first end and the second end of the electric heater 6 are respectively connected between a first switch control end 2 and the heat sensitive bimetal strip 5 in serial manner. The tilting end of the heat sensitive bimetal strip 5 is hinged with one end of a tilting metal strip 8 to form a hinge point 11, while a swing contact 12 on the other end of the tilting metal strip 8 is arranged in the position of a contact point 10 of a second switch control end 3. The middle part of the tilting metal strip 8 is provided with a spring 9 which is fixed on the shell 1. The line formed at two ends of the spring 9 is in the range which the heat sensitive bimetal strip 5 is heated to deform and allow the hinge point 11 to swing. The shell 1 is provided with an adjusting cam 13 which can go against the elastic sheet 4.

Description

technical field [0001] The invention belongs to the technical field of temperature control and relates to a temperature regulating switch. Background technique [0002] The existing stepless adjustment switch includes a housing, in which there are two switch control ends, a heat-sensitive bimetal sheet that can be tilted is provided on one of the switch control ends, and a heat-sensitive bimetal sheet is provided on the heat-sensitive bimetal sheet. A contact that makes contact with another switch control terminal. An electric heater is arranged on the heat-sensitive bimetal sheet, and one end of the electric heater is connected with a power supply terminal, and the other end is connected with the heat-sensitive bimetal sheet. A cam for adjustment is provided in the casing, and the cam abuts against the root of the heat-sensitive bimetal, and the cam can be adjusted to rotate the cam to change the angle of the heat-sensitive bimetal. [0003] When a voltage is applied to t...
