    Isolator Switch Features

    • The acceleration mechanism that is released instantaneously by the spring accumulator achieves fast switching or breaking (13.8 m/s), which is independent of the operating handle speed and greatly improves the arc extinguishing capability.
    • The outer shell made of glass fiber reinforced unsaturated polyester resin has good flame retardancy, dielectric properties, carbonation resistance and impact resistance.
    • Parallel double breaks have self-cleaning action.
    • All contacts have two separate contact faces. The isolation distance is large. When the position is “0”, the handle can be locked with three locks at the same time, which can reliably avoid misoperation.

    Is it easy to install?
    I really want to order this isolator switch but I hesitate. Is it easy to install? Could i use this switch for an on/off switch for a dc motor? How about the longevity of the switch for this type of use?

    Yes, it is easy to install and it can only switch for ac motor. It is not flimsy plastic, it is thick and durable and has no problem standing up to repeated start-stop cycles daily.
