Thermoswitches is an electric electric controller for setting the temperature in the closed space. Thermostats (thermoswitches) are typically connected to a heat sink (heater) or a cold storage device, to keep the space in constant temperature when the device plugged in and to be controlled. Thermodisc operation is such that when the temperature reaches the desired setting temperature, the thermoswitch cut off the electrical circuit of the device, and when the temperature is lowered by 3 to 5 degrees from the set point, it will cut off the electrical circuit in half and the device will start to work. ASAHI KEIKI Japan is available in ranges from 40 to 120 degrees and has UL, CE and ISO9001 standards with a phenolic body material.
