According to the working principle of the invention, under normal temperature, the temperature-sensing multi-metal sheet 10 senses the change of environmental temperature and generates corresponding linear deformation displacement, so that the transmission fusible alloy column 11, the transmission limiting insulator 18, the floating lower reed 25 and the floating upper reed 23 are pushed to achieve the purpose of displacement transmission, and the position of the convex mounting strip 37 (shown as the position B in figures 9 and 10) of the elastic sheet on the floating upper reed 23 is the position to obtain corresponding linear high-low displacement change.
The A point position is set to be fixed for explanation, and the on-off principle of the contact floating type adjustable temperature controller switch is as follows:
1) when the position B is lower than the position A, one end of the energy storage elasticity of the U-shaped spring piece 24 takes the position A as a fulcrum, and the position B at the other end is pressed outwards and downwards, so that the silver contact I27 at the end part of the floating upper reed 23 moves downwards, and the switch is closed;
2) when the position B is horizontal to the position A, one end of the energy storage elasticity of the U-shaped spring piece 24 takes the position A as a fulcrum, and the position B at the other end is only subjected to outward horizontal force, so that the silver contact I27 at the end part of the floating upper reed 23 keeps the original state;
3) when the position of the point B is higher than the position of the point A, one end of the energy storage elastic force of the U-shaped spring piece 24 takes the point A as a fulcrum, and the point B at the other end is pressed outwards and upwards, so that the first silver contact 27 at the end part of the floating upper reed 23 moves upwards, and the switch is switched off.
