Overview
The Schlegel Elektrokontakt RRJSSA28 is a momentary push-button switch designed for precise control in industrial panel applications. This unit features a 1 x 45° switching function, providing a specific directional input. It requires a standard 22.3 mm round panel cutout for installation, a common size in control systems. The switch is finished with a silver bezel, offering a clean and professional aesthetic suitable for various control panel designs. Notably, this model does not include illumination or labeling options, making it ideal for applications where a minimalist interface is preferred or where external labeling is managed separately. The momentary action ensures that the circuit is only active while the button is pressed, returning to its default state when released. This characteristic is essential for functions like starting, stopping, or signaling temporary commands in machinery, automation, and electrical control systems. Manufactured by Schlegel Elektrokontakt, the RRJSSA28 (SKU: RRJSSA28) is built for reliable operation in demanding environments. Its construction and design prioritize functional simplicity and dependable performance for critical control tasks. The country of origin is Germany (DE).
