Product Introduction
The LFF series auxiliary switches are one of the supporting components for high-voltage complete sets of equipment. They are suitable for controlling the closing, opening, interlocking, and signal circuits of various high-voltage switch operating mechanisms, and can also be used as conversion or combination switches.
The LFF series auxiliary switches feature two wiring methods: plug-in and crimping. Moreover, the wire outlet direction is on one side, making them convenient for use in Spaces with limited space.
The LFF series auxiliary switches can achieve various on-off timing changes by altering the assembly direction inside. The contact parts are made of high-quality copper, and the surface is silver-plated to enhance the connection reliability and breaking capacity.
