30 mm Selector Switch for Control Panels
The CUTLER-HAMMER 10250T21KB is a non-illuminated selector switch designed for industrial control panels and machinery. It provides three maintained positions with a black polymer knob and chrome zinc bezel. The switch carries a 10A contact rating at 600V AC with NEMA A600/P600 designation. It suits operators who need reliable manual switching in harsh environments.
Panel Cut-Out and Voltage Compatibility
Verify that the mounting panel has a standard 30 mm cut-out for the operator head. Confirm the control circuit voltage does not exceed 600V AC to match the contact rating. The IP68 and NEMA 4X ratings mean the switch withstands wash-down and corrosion, but the enclosure must provide the same sealing. Ensure the cam 3 switching sequence (XO, OO, OX) matches the required logic.
Two Normally Open Contacts in a Metal Housing
The switch supplies two normally open contacts that close according to the cam 3 sequence across the three positions. Its metal basic construction and zinc bezel mount securely in panels rated NEMA 12, 13, 3, 3R, 4 or 4X. The maintained action in every position frees the operator from holding the knob. No illumination or key removal features are included, keeping the assembly simple for basic control tasks.

Questions about this item
Does the selector switch include mounting hardware or must I order a legend plate separately?
The switch ships as a complete 30 mm operator with cam 3 and 2NO contacts installed; no legend plate or additional hardware is mentioned in the product details.
How do I choose between cam 3 and other cam options for my control sequence?
Cam 3 gives the contact state XO in position A, OO in position B and OX in position C, matching a maintained three-position sequence where the centre position opens both contacts.
What does the 10 A at 600 V AC rating mean for a motor starter circuit?
The A600/P600 designation confirms the contacts can make and break 10 A at 600 V AC in typical industrial motor control applications.
