NS00 Cam Switch. Robust.

The NS00 is a very robust rotary cam switch with 6 mm diameter metal square shaft, aluminum nameplate, and cam-actuated contacts. The switch contacts, embedded in double contact modular blocks, with positive break by the cam discs, are available in three different versions. A special gold-plated version is suited for low voltage applications. A silver contact editions is designed for standard applications. And, finally, an edition using a permanent magnetic blowout is for direct current set-ups.

The NS00 rotary cam switches handle control tasks in switch panels, control stations and on-deck control stations. The can be equipped with metal notched discs from the Spohn & Burkhardt modular program, with customised positive-locking flanged potentiometers or with encoders that fit the customer's specifications.
