Push button, 22 mm, round, plastic, yellow, flat, tactile, with holder 1S, spring-loaded connection. SIRIUS ACT push button 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 suitable for industrial use and outdoor applications. Even cleaning with high-pressure jets 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 greater flexibility. The graphical online configurator conveniently supports the selection and ordering of individual devices, housings, and labeling. Extensive documentation (e.g., manual, 3D data, connection diagram) is available. Available versions: multiple colors, illuminated/non-illuminated, with/without labeling, latching/tactile operation, various push button and front ring heights. Note: Complete device, delivery includes holder and modules. SIRIUS ACT - Performance in Action for control and signaling. Easy to install, simply strong, simply perfect.
