Temp-control switch

Abstract

A mechanical temperature control switch turned on or off by a temperature control circuit includes: one end of a temperature-sensitive metal rod is contacted with a first stage lever, one end of which is fixed to a vertical rod, the other end of the rod is contacted with a third lever, which is electrically connected with a first connection post fixed on a shell by a lead, its tail is close to a second connection post, a small round ball and a delay bolt are set between the second post and the latter part of the third stage lever, when the action temperature of the temperature control switch is adjusted, a primary line rod is sleeved on a triangle short post and a round scaling disk is sleeved on the triangle part of the bolt to accurately adjust the temperature, which amplifies variance volume of a temperature-sensed metal rod along with the temperature by many times.

Description

technical field [0001] The invention relates to a mechanical temperature control switch which is turned on and off by a temperature control circuit. Background technique [0002] At present, the known temperature control switches are divided into mechanical type and electronic type. Except for the bimetallic temperature control switch in the mechanical type, other temperature control switches are more complicated in structure and larger in size, but the accuracy of the bimetallic temperature control switch Low, except for bimetallic and resistive temperature control switches, other temperature control switches are more expensive. Currently known temperature control switches each have their disadvantages, and there is no temperature control switch with simple structure, small volume, high precision and low price. Contents of the invention [0003] In order to overcome the disadvantages of the existing temperature control switch, the present invention provides a temperature...

[0002] At present, the known temperature control switches are divided into mechanical type and electronic type. Except for the bimetallic temperature control switch in the mechanical type, other temperature control switches are more complicated in structure and larger in size, but the accuracy of the bimetallic temperature control switch Low, except for bimetallic and resistive temperature control switches, other temperature control switches are more expensive

At present, the known temperature control switches have their own shortcomings, and there is no temperature control switch with simple structure, small volume, high precision and low price.
