An indoor earthing switch serves as a mechanical apparatus employed to dissipate static charges from equipment and circuits during maintenance operations. Its primary purpose is to safeguard the well-being of maintenance personnel when conducting power outage maintenance. The switch is specifically engineered to endure current during exceptional events, such as short circuits, for a predetermined period, while remaining inactive in carrying load current under typical circumstances. Moreover, it is designed to function reliably even in high-altitude environments, ensuring its suitability for such conditions.

When placing an order, please specify the requirement for an indoor earthing switch that can withstand current for a specific duration during abnormal situations like short circuits. It is important to note that the switch should not pass load current under normal conditions. Additionally, kindly mention the need for the switch to be suitable for high altitude usage, ensuring its reliable operation in such environments.
