Push button, 22 mm, round, metal, high gloss, yellow, flat, tactile, 1S, spring terminal connection. The SIRIUS ACT push button is designed for switching and controlling electrical consumers. Under the SIRIUS ACT brand, Siemens offers a unique portfolio of control and signaling devices with worldwide 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 high-pressure jets is possible. Neither dust, oils, nor aggressive lyes 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 greater flexibility. The graphical online configurator conveniently assists in selecting and ordering individual devices, housings, and labels. Extensive documentation (e.g., manual, 3D data, connection diagram) is available. Available versions: multiple colors, illuminated/non-illuminated, with/without labeling, latching/tactile actuation, various push button and front ring heights.
