ksd301snap action thermostat is small-size bimetal thermostat series with a metal cap,which belongs to thermalrelays’family.the main principle is that one fumction of bimetal discs snap action under the change of sening temperature.the snap action of disc can push the action of the contacts through the inside structure,then caused on of off of the circuitfinally.the main characteristics are the fixation of working temperature,the reliable snap action,less flashover,longer working life and less radio interference.

将试样两引线分别接在测试设备的夹具上，通上10ma左右的电流（不超过100ma），用一发光二极管指示电流的通断，然后将试样放入专用测温设备内，（测试设备内温度应均匀，加热升温速度可控制）温度计探头应贴近试样，控制检测设备温度以0.5～1℃/min的速率升温,当发光二极管熄灭时,记下温度计读数即为试样的动作温度。
