Rotary Switch Diagram
Working Conditions
1. The ambient air temperature ≤ +40 ° C, and the average temperature within 24 h ≤ +35 ° C.
2. The lower limit of ambient air temperature ≤ -25 °C.
3. The altitude of the installation location is ≤2000m.
4. When the maximum temperature is +40 °C, the relative humidity of the air does not exceed 50%, and the higher relative humidity can be allowed at lower temperatures, for example, 90% at 20 °C. Special measures should be taken for condensation that occasionally occurs due to temperature changes.
High quality changeover switch for sale, 40A, 2 position rotary switch is mainly used for AC 50Hz, can be used for main switch of ventilation equipment, air conditioning and water pump system, ideal for power switches in power lines.
