5 Features

5.1 Miniaturized: compact structure, small volume, ideal performances.
5.2 Finger shield: finger shield function prevents from electric shock caused by contacting live parts accidentally.
5.3 Reliability: (1) Revolutionary new type contact operating mechanism guarantees movement of positive contacts, it not only can be used for breaking of contacts, but also can be used for making of contacts, make the position of switch operating handle be accordant with contact position, therefore, it provides high making and breaking capacity for normal control. (2) All contacts of switch have double actions of electrical apparatus switching and self-cleaning. During operation, surface of contact would be wiped up due to slide closing.
5.4 Safety: insulation distance of opened contacts of switch is as long as 7~8mm, advance beyond the safety requirements of VDE0113. Flexible installation type: the switch can adopt both panel type and base mounting type, the latter also can be installed with screws or guide-rail of 35mm conveniently and safely.
5.5 Modularized: flexible module system provides the strongest flexibility and adaptability for regulation of switch position, it has three-pole and six-pole standard modules, it is able to add additional contact block, shielding case, padlock handle, door interlock and other accessories easily, this characteristic especially suitable for location change.
5.6 Convenient installation: the built-in screw protects it from slipping during manual operation, which enables the pneumatic or electric tool to exert their best efficiency, guaranteeing safety and quick speed of installation. Switch with seal box: the switch can be equipped with indoor or outdoor insulated box. It can be equipped with steel sheet or stainless steel box body (for strong corrosive environment) and hot moulding box (with high impact strength). Ingress protection level is IP40-IP65.
