30 mm Selector Switch for Industrial Panels

This Siemens selector switch fits a 30 mm panel cut-out and provides three maintained lever positions. It carries a 10 A contact rating at 600 V AC and meets NEMA 1, 3, 3R, 4, 4X, 12 and 13 as well as IP20 and IP66 sealing. The black plastic lever and zinc bezel suit standard control stations and machine consoles.

Replaces Two-Position or Momentary Switches

Upgrading from a two-position selector adds a third distinct circuit state without enlarging the cut-out. The jump is worth it when a process needs an explicit off or neutral position between two active modes, such as hand-off-auto motor control. Momentary switches cannot hold position, so this maintained-action cam C unit is the correct choice when the operator must leave the selector in any of the three settings.

Three Maintained Positions with Cam C Logic

Cam C delivers the switching sequence XO, OO, OX across positions A, B and C using a single 1NO/1NC contact block. This comfortably handles start-stop-run or forward-off-reverse sequences in one operator. It runs out when an application demands more than one contact block per position, keyed access, illuminated indication or a different cam sequence not provided by this model.

Questions about this item

What panel cut-out diameter does the 30 mm selector switch require?

The operator is designed for a 30 mm mounting hole in the panel.

Which contact block configuration matches the maintained action at positions A, B and C?

Use a 1NO/1NC contact block; the cam C gives XO at position A, OO at position B and OX at position C.

When should the contact block be inspected or replaced under a 10 A, 600 V AC load?

Plan inspection after the rated electrical endurance cycles; replace if contact resistance rises or switching becomes unreliable.
