Product Description-----------------------------------------------------------------------------------------------------------------------------------------------------------
KSD 309 Series Thermostat is a commonly used bimetallic thermostat in various applications. It is a type of thermal switch that operates based on the principle of thermal expansion and contraction of two dissimilar metals.
Advantages Of KSD309 Thermostat
1. Temperature Sensing And Control: The KSD309 thermostat is designed to sense temperature changes and provide control functions based on the set temperature thresholds. It can open or close electrical contacts to regulate the temperature in a specific system or device.
2. Bimetallic Construction: The thermostat utilizes a bimetallic strip that consists of two metal layers with different coefficients of thermal expansion. When the temperature changes, the bimetallic strip bends due to the differing expansion rates, triggering the switching action of the thermostat.
3. Snap-Action Switching: The KSD309 thermostat employs a snap-action mechanism, meaning that once the temperature reaches a certain point, the bimetallic strip rapidly snaps to a different position, either opening or closing the electrical contacts. This quick switching action ensures fast response and accuracy in temperature control.
4. Compact And Reliable Design: The KSD309 thermostat is compact in size, making it suitable for various space-constrained applications. It is designed to be reliable, with durable construction and stable performance over an extended period.

Straight Pins:
Bend Pins:
1. PCB Pins: Some KSD309 thermostats may come with PCB (Printed Circuit Board) pins, which are designed for direct insertion into pre-drilled holes on a circuit board.
2. Straight Pins: This configuration features straight pins extending from the body of the thermostat. These pins are typically soldered onto a circuit board or connected using appropriate connectors.
3. Right-Angle Pins: In this configuration, the pins of the KSD309 thermostat are bent at a right angle. This allows for horizontal mounting on a circuit board or facilitates connections in tight spaces.
Application------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1. Electric Water Heaters: The KSD309 thermostat is frequently used in electric water heaters to regulate and maintain the desired water temperature. It ensures that the heating element is activated or deactivated based on the set temperature threshold, providing efficient and safe water heating.
2. Electric Kettles: KSD309 thermostats are employed in electric kettles to control the heating element and maintain the water temperature at a desired level. They help prevent over-boiling and ensure the kettle switches off when the water reaches the set temperature.
3. Coffee Makers: Coffee makers utilize the KSD309 thermostat to control the temperature of the water during brewing. The thermostat helps maintain the optimal brewing temperature for extracting the desired flavors from the coffee grounds.
4. Toasters: KSD309 thermostats are used in toasters to regulate the toasting process. They ensure that the toasting elements heat up to the desired temperature, allowing precise browning of bread or other food items.
5. Heating Appliances: The KSD309 thermostat is applied in various heating appliances like electric ovens, electric fryers, and electric grills. It controls the temperature inside the appliance, ensuring consistent and accurate heating for cooking or baking purposes.
