The mushroom pushbutton M22S-DRP-G from Eaton belongs to the RMQ-Titan range and is supplied as a single unit. It features a mushroom-shaped design and is configured as a latching type. The colour of the mushroom head and the button faceplate is green, with the faceplate being unmarked (blank). The front ring is black. The pushbutton is designed for mounting in panels with dimensions of 22 mm x 22 mm, making it suitable for standard socket and switch panels in industrial electrical engineering. The latching or momentary function can be changed directly on the device, enabling flexible use in various applications.

Applications
The mushroom pushbutton is designed for use in industrial control and operator systems, particularly in environments requiring high mechanical and electrical reliability. Due to its protection rating of IP66, IP67 and IP69K, the device is dust- and waterproof, making it suitable for outdoor use or in damp, dirty, or heavily stressed production environments. The IP69K rating also allows cleaning with high-pressure water jets, which is relevant in the food industry or for hygiene requirements.

Functions and Equipment in Detail
The pushbutton is latching, meaning that after actuation, the button remains in the actuated position until pressed again. This function is typical for start or stop buttons in drive control systems. The ability to change the latching or momentary function directly on the device offers flexibility during commissioning and adaptation to different applications. The faceplate is green and unmarked, allowing it to be individually labelled or combined with a label holder to clearly indicate its function.

Technology Explained Simply
The protection rating IP66, IP67 and IP69K guarantees high protection against dust and water. IP66 protects against strong water jets from any direction, IP67 against temporary submersion, and IP69K against hot steam and high-pressure water jets. These properties make the pushbutton suitable for demanding industrial environments. Connection to SmartWire-DT is possible, as the device is equipped with RMQ-SWD terminals. This enables integrated communication in SmartWire-DT networks, which are used in modern industrial control systems.

Compatibility and Accessories
The mushroom pushbutton M22S-DRP-G can be combined with various accessories to extend functionality and identification. Examples include label holders such as M22S-ST-F10 (ARRET MARCHE), M22S-ST-D10 (AUS EIN), or M22S-ST-GB1 (START), which provide clear marking of the button function. Other compatible components include contact elements such as M22-CK01 (1NC front) or M22-CKC01 (1NC bottom), as well as caps such as M22-H5 or M22-H4, which enhance mechanical protection. For mounting on DIN rails, the adapter M22-IVS is available. The use of mounting adapters such as M22-ADC4 (4-way) or M22-ADC (3-way) enables secure and dust-tight installation in enclosures.

Mounting and Installation
The pushbutton is installed into a panel opening of 22 mm x 22 mm. Mounting is done by inserting it into the designated cutout, with the front rings providing mechanical fixation. Electrical connection is made via RMQ-SWD terminals, designed for integration into SmartWire-DT systems. The use of label holders and caps is done after installation and serves identification and additional protection.

Advantages in Operation
The high protection rating IP69K enables robust use in dirty or damp environments. The ability to change the latching or momentary function directly on the device increases flexibility during commissioning. Compatibility with SmartWire-DT systems supports modern, networked control solutions. The use of accessories such as label holders and caps allows individual adaptation to the specific application, improving operability and safety.

The pushbutton complies with standards IEC/EN 60947 and VDE 0660, which apply to the safety and reliability of switching devices in electrical engineering.
