Auto Reset Normal Close NC Bakelite Snap Action Bimetal Disc Thermostat 10A 250V OFF 120C ON 110C
Features Of The Bimetal Disc Thermostat 10A 250V
1) Contact Type: Single Pole Single Throw
2) Terminal Strength
The 250 terminal can withstand 10kg in the axial direction and 5kg
in the radial direction, and the 187 terminal can withstand 8kg in
the axial direction and 4kg in the radial direction for 10sec
without causing functional problems.
3) Appearance
No rust, cracks, deformation and stains.
4) Shapes
Shape and size, according to customer samples or figure.
Structure Of The Bimetal Disc Thermostat 10A 250V
1) Bimetal momentary automatic temperature control switch
When the temperature reaches the temperature range specified by the
user, the temperature sensing surface feels the temperature change,
and then transmits the temperature change to the bimetal strip to
play the function of on/off. The temperature control switch is
composed of a temperature sensing part, a switch part, a base part,
an operation part and an electrical connection part.
2) Temperature sensing part
This part is composed of a bimetallic sheet and a metal aluminum
cover for sensing temperature, which is used for sensing
temperature.
3) Switch section
The function of this part is to turn on and off the current, and it
consists of fixed contacts, moving contacts, fixed connection
plates, spring sheets and rivets.
4) Base part
This part is used for insulation protection, supporting the
temperature sensing part and the switch part.
5) Operation Section
This part is composed of a guide frame and an action rod, and its
function is to transmit the mechanical movement of the bimetal to
the switch part.
6) Electrical connection part
This part consists of the connection of external terminals and
internal rivets.
