Illuminated Multi-Head Operator
This Siemens 3SU1001-3BB42-0AK0 is an illuminated multi-head operator featuring two distinct heads in a 22 mm mounting size. One head uses an extended button while the other uses a flush button, both with momentary action. The unit displays green and red legend colours marked I/O for clear status indication. It is built for industrial control panels and machinery interfaces.
Suitable Applications
This operator suits panels requiring a compact start/stop or forward/reverse station with illuminated feedback. The IP69K and NEMA 4X ratings support wash-down environments in food, beverage or pharmaceutical plants. Buyers needing maintained switching action, a single-head layout or an integrated lamp module should consider other devices.
Decisive Specification
The 22 mm mounting diameter determines panel cut-out compatibility and spacing. Verify the cut-out matches this dimension before ordering. The lamp voltage and lamp type modules are not included and must be sourced separately to complete the illuminated function.

Questions about this item
Should I pick the version with two heads or a single-head alternative?
This model is the two-head version with one extended and one flush button, both 22 mm round, marked I and O for on/off control.
What does the IP 69K rating mean once the unit is mounted?
It withstands high-pressure, high-temperature wash-downs, so the operator stays sealed in food-processing or outdoor equipment.
How do the NEMA 1, 2, 3, 3R, 4, 4X ratings limit where I can install it?
They certify the enclosure against dust, water, oil and corrosion, allowing indoor and outdoor mounting in harsh industrial environments.
