Overview
The Schlegel Elektrokontakt QXJSSA27E is a compact, square momentary pushbutton switch engineered for precise control in industrial automation, machinery interfaces, and operator panels. Designed with a 24 x 24 mm panel cutout and a 27 x 27 mm front dimension, this switch integrates seamlessly into control stations requiring reliable tactile feedback. The black bezel provides a clean, professional aesthetic while maintaining durability in demanding environments. Key specifications include a 6 mm travel distance and IP65/IP67 ingress protection, ensuring resistance to dust and water ingress for challenging industrial applications. The switch features a twist-to-release mechanism (right or left), allowing for secure actuation and preventing accidental operation. Faston terminals and screw connections provide flexible wiring options, accommodating both quick-connect and traditional termination methods. This momentary switch is ideal for applications where temporary circuit activation is required, such as emergency stop reset, mode selection, or momentary control functions. Its compact design makes it suitable for space-constrained control panels, while the robust construction ensures long-term reliability. The QXJSSA27E is part of Schlegel Elektrokontakt’s QUARTRON-JUWEL series, a line known for precision engineering and high-quality industrial components.
