Industrial Selector Switch 30mm
This SIEMENS selector switch fits a standard 30 mm panel cut-out and provides three operating positions with a momentary, maintained, momentary action sequence. The extended lever operator is black plastic on a metal body with a zinc bezel finished in black. Rated at 10A at 600V AC with an A600 NEMA contact designation, it carries a single normally open and normally closed contact block.
Panel Builders Needing Three-Position Control
The switch suits control panels that require a three-position selector with the specific momentary-maintained-momentary cam sequence. It is not suited for applications needing four or more positions, keyed operation, illuminated operators, or a different cam arrangement. Builders requiring a maintained action in every position should choose a different cam type.
Cam C Three-Position Sequence
The Cam C mechanism defines the contact state at each of the three positions and fixes the momentary-maintained-momentary operation pattern. This cam type determines whether the switch matches the control logic of the machine. Verify the required cam letter against the wiring diagram before installation.

Questions about this item
How do I mount this 30 mm selector switch in a panel cutout?
Insert the operator through a 30 mm hole, secure the locking nut from behind, then snap the contact block onto the operator until it clicks — skipping the click leaves the contacts loose.
Which parts wear out first on a 10A 600V AC selector switch with cam C?
The 1NO/1NC contact block and the plastic operator head see mechanical wear; replace the contact block when switching feels vague or contacts show pitting.
At what point does the IP66 seal or NEMA 4X rating become the limiting factor during continuous operation?
The IP20 rear terminals stay protected only if the enclosure gasket remains intact; heat and vibration can degrade the seal before the 10 A contacts reach end of life.
