2. The shell made of unsaturated polyester resin reinforced by fiberglass provides great flame resistant performance, impact resistant performance, dielectric performance and safe operation.
3. Parallel double breakpoint contact possesses self-cleaning functions.
4. All the contact materials are copper alloy plated with silver, with two separation contact surfaces.
5. Large distance of insulation.
6. Be on "0" position, the switch handle can be locked with three locks at the same time and thus avoid error operation.
