Electrical performance:16(3)A-250V～10(1.8)A-400V～ Product life:> 100,000 times Electric strength:AC2000V/1min Contact resistance:≤ 50mΩ The minimum current:200mA Tide insulation resistance:≥10MΩ Normal insulation resistance:≥100MΩ The temperature response rate:≤ 1.0°C/min Disconnect the temperature:the action temperature is plus or minus 5 degrees Heat control Principal: when the Tem is set at 35℃,the probe 1 and 2 is closed when the sensed temperature is lower then 35,it stops heating until 1 and 2 disconnected when the sensed temperature reached 35. Cooling Principal: Set the temperature at 35,the condensor stop working when sensed tem is lower then 35 when 1 &4 disconnect.The condensor began to cooling when the teperature reaches 35,the 1 and 4 will closed.Thus a setting temperature is kept by such circulation. Note: Please allow 1-3mm error due to manual measurement.pls make sure you do not mind before you bid. Due to the difference between different monitors,the picture may not reflect the actual color of the item.Thank you! Package Includes: 1x Temperature Control Switch
