The article from Busch Jaeger, type 1789-866, manufacturer's number 2CKA001751A2957, is a single-piece stainless steel toggle used as a cover for flush-mounted switches and push buttons. It is part of the pur edelstahl design line and is specifically intended for use with off switches, changeover switches, cross switches, push buttons, and control changeover switches. The toggle features an anti-fingerprint surface that minimizes fingerprints and helps maintain its visual appearance over time. The surface is matte and untreated, preserving the natural stainless steel look. The color corresponds to the stainless steel standard, with the toggle featuring a small red cap serving as a visual marker.

Applications

The toggle is designed for indoor use where a robust and aesthetically pleasing switch cover is required. It is particularly suitable for residential and commercial spaces requiring a modern, minimalist design. The cover is mounted on flush-mounted switches already installed in the wall cladding. It is used exclusively as a cover — it is not suitable for bus system push button connections.

Functions and Features in Detail

The toggle is designed as a single toggle and serves solely as an optical and mechanical cover for the switch beneath. It does not include integrated control windows, light outlets, or labeling fields. The surface is not tactile, making it unsuitable for barrier-free applications. The small red cap serves as a visual indicator, for example, to distinguish switches with different functions. The toggle is not equipped with interchangeable lenses or symbols.

Technical Explanation

The toggle is made of stainless steel, a material known for its corrosion resistance and mechanical strength. The anti-fingerprint treatment reduces the visibility of fingerprints, improving maintenance and appearance during daily use. The matte surface minimizes reflections and creates a discreet look. The protection class IP20 means the toggle is protected against contact with fingers and against solid foreign objects larger than 2.5 mm, but not against water or dust. The impact resistance IK03 indicates that the toggle is protected against minor mechanical stress such as light bumps or pressure, but not against hard or repeated impacts. The mounting is done via a clamp fastening, enabling secure and easy installation on flush-mounted switches.

Compatibility and Accessories

The toggle is specifically designed for flush-mounted switches and push buttons in the pur edelstahl series. It is not suitable for bus system push button connections. Compatibility is limited to the mentioned switch types: off switches, changeover switches, cross switches, push buttons, and control changeover switches. There is no information available on additional accessories or replacement components that can be combined with this item.

Installation and Mounting

Mounting is done via clamp fastening onto already installed flush-mounted switches. The toggle is simply clipped onto the switch and fits securely. No additional tools or mounting aids are required. The dimensions are 63 mm width, 63 mm height, and 20 mm depth, which is a standard size for flush-mounted switch covers. Installation is intended for indoor use only, as the IP20 protection class does not allow use outdoors or in damp areas.

Operational Advantages

The toggle offers a robust and aesthetically pleasing cover, distinguished by its stainless steel surface and anti-fingerprint treatment. The small red cap allows for easy visual differentiation between switches. The clamp fastening ensures quick and secure installation. The IP20 protection class and IK03 impact resistance ensure reliable operation in indoor environments under normal conditions. The toggle is not suitable for barrier-free applications, as it is not tactile.
