This creation is a breeding box for reptile pets. Generally, the existing technology provides a warm light, without the constant temperature control and the addition of a thermostat. However, when the heating increase or decrease is different from the thermostat control, it is not in line with the reality. This creation is mainly to provide a three-section three-cut switch for manual control, closing action or instrument control of heating lamps, fans and humidifiers, so that the living space can become a livable environment for reptile pets.
