Knob switch, illuminated, 30 mm, round, metal, matte, yellow, knob, short, front ring for flat installation, 3 switching positions I-O-II, latching, switching angle 2x45°. The SIRIUS ACT knob switch is used for switching and controlling electrical consumers. Under the brand name SIRIUS ACT, Siemens offers a unique portfolio of control and signaling devices with global product approvals in three modern design series made of robust real metal and high-quality plastic. The innovative snap-on concept simplifies installation to the extent that only one hand and no special tools are required. For mounting holes, non-threaded holes are sufficient, as a 100% anti-twist protection is already integrated. Thanks to the consistently high protection class, the robust devices are industrial-grade and suitable for outdoor use. Even cleaning with a high-pressure jet is possible. Neither dust, oils, nor aggressive alkalis can disrupt reliable operation. In addition to standard wiring, most devices can also be connected to the control system via PROFINET, AS-Interface, or IO-Link. This reduces your wiring effort, minimizes sources of error, and provides more flexibility. The graphical online configurator comfortably supports the selection and ordering of individual devices, enclosures, and labeling. Extensive documentation (e.g., manual, 3D data, connection diagram) is available. Available versions: several colors, 2-4 switching positions, short/long knob or rotary knob, illuminated/non-illuminated (illumination can also be retrofitted), latching/tactile operation. Note: Individual device, holder, and modules must be ordered separately. SIRIUS ACT - Performance in Action for control and signaling. Easily installed, simply strong, simply perfect.
