Switch modular design, suitable for breaking the circuit or connected to the electrical isolation of the above is only used with electrical isolation. Switch with spring energy storage, instantaneous release of the body and accelerate the closing off both connected in parallel with the double-break point contact structure, which greatly improves the product's electrical performance and mechanical properties. Switch to glass fiber reinforced unsaturated polyester plastic film and manual operating handle, with high dielectric properties, protection capability and reliable operation of safety. According to the need to provide normally open and normally closed auxiliary contact on the board to install special plate after plate front panel wiring to meet customer's needs.
