Overview
The Schlegel Elektrokontakt JRMSSA17E is a compact, panel-mounted maintained switch designed for industrial control systems requiring precise, reliable switching. This 22.3mm diameter switch features a silver bezel and delivers a maintained switching function with a 1x90° direction-angle, ensuring consistent operation in demanding environments. The unit is rated for IP65/IP67 protection (front/rear with M12 connector), making it suitable for use in harsh industrial conditions where dust and moisture resistance are critical.
Built to EN 60947-5-1 standards, the JRMSSA17E supports a maximum switching capacity of 35V AC/DC at 4A (AC) or 2A (DC), with silver-nickel (AgNi) contact material for reliable electrical performance. The switch has a front bezel height of 2mm and a travel distance of 2.3mm, providing tactile feedback while maintaining a low profile in control panels. Its round design and minimalist construction eliminate unnecessary features like illumination or labeling, reducing complexity and potential failure points.
Ideal for machinery interfaces, control panels, and automation systems, the JRMSSA17E is manufactured in Germany by Schlegel Elektrokontakt, a leader in industrial switching solutions. The switch is compatible with standard 22.3mm panel cutouts and integrates seamlessly with M12 connector systems for secure, vibration-resistant connections. With no moving parts exposed to the rear and a robust front seal, this switch ensures long-term durability in applications ranging from manufacturing to process control.
