C&K Components has developed a new family of configurable switches with a quick connector and a low-profile panel depth. Designated the RAFIX 22 FS series, the switches are available in pushbutton, selection, key, signal lamp and emergency-stop configurations, and require only 27 mm of mounting depth behind the front plate.
All these components are IP65 splash-water protected in accordance with DIN standards, and the mounting diameter in the front plate is 22,3 mm in accordance with IEC 60947 specifications. These switches also feature a quick connector that supports a modular installation concept, allowing them to be plugged into the panel and locked firmly into place. This also lets the user store individual switch elements separately and configure them during final assembly to meet application-specific needs.
The emergency-stop switches are designed with a positive mechanical movement sequence. A certain operating force must be exerted at the push cap in order to prevent inadvertent operation. When pressed, the pushbutton latches and is reset by turning the switch in a clockwise direction.
Wiring of the RAFIX 22 FS series switches is carried out via a 2,8 x 0,8 mm blade terminal, or via the soldering terminals in the quick connector. A ridge between the contacts prevents short circuits, even under tensile load of the connection cable. Illuminated versions of the pushbutton and signal lamp switches are also available, with LEDs in five different colours which can be clicked into the switches from behind using flat contactors. All switches are available with gold contacts for electronic applications (minimum 5 V/1 mA) or silver contacts for mains voltage (maximum 250 V/4 A).
