The Goobay KNX 3 is a miniature toggle switch with three positions, designed for use in electronic devices and model building applications. The switch features three solder terminals for electrical connection and enables a switching sequence of ON – OFF – ON. It is equipped with a metallic lever that ensures precise and mechanically robust operation. The compact design with dimensions of 12.9 mm (length), 8 mm (width), and 33 mm (height) makes it particularly suitable for space-saving installation solutions in small projects or DIY applications.

Toggle switch with three positions provides a clear and unambiguous switching logic, which is required in many electronic circuits. The switching sequence ON – OFF – ON allows switching between two active states and an off state, which is useful for example in controlling relays, lamps, or small motors. The maximum load capacity is 6 A at 125 V or 3 A at 250 V, making the switch suitable for a wide range of applications in low-voltage technology. The specified values refer to the electrical load that the switch can safely switch without overheating or contact wear.

Solder terminals at the three connection points enable simple and secure mounting on printed circuit boards. The solder terminals are designed to ensure a secure electrical connection and also provide mechanical stability. The use of solder terminals is common in electronics manufacturing, as they enable a durable and reliable connection, especially in applications where mechanical stress or vibrations may occur.

Metal lever ensures high mechanical strength and long service life of the switch. The lever is dimensioned to be easy to operate without breaking or deforming under frequent use. The metallic construction also provides good protection against wear and corrosion, increasing the reliability of the switch in various environments.

Miniature design with the specified dimensions makes the switch particularly suitable for use in compact devices. The low height of 33 mm and narrow width of 8 mm allow integration into devices where space is limited. The length of 12.9 mm is also designed for efficient space utilization. These dimensions are typical for switches used in model building, small projects, or electronics development.

Applications include particularly DIY construction, model building, and the development of electronic devices where a small, robust, and reliable switching solution is required. The switch is not intended for use in household appliances or industrial electrical engineering, as it does not meet specific protection or safety standards. Use is limited to applications where the electrical load remains within the specified limits.

Compatibility and accessories refer to use with standard printed circuit boards and soldering techniques. There are no specific accessories recommended or supplied by the manufacturer. Installation is done by soldering the three pins to the corresponding circuit traces. No additional mounting aids or tools are required, as the solder terminals can be directly attached to the circuit board.

Mounting and installation are performed by soldering the three pins to the circuit board. The positioning of the switch should correspond to the switching logic and mechanical requirements of the specific application. The solder joints must be clean and secure to ensure a reliable electrical connection. Mechanical stress on the lever should be minimized during mounting and operation to ensure a long service life of the switch.

Operational advantages lie in the combination of compact design, high mechanical stability, and sufficient electrical load capacity. The switch is easy to mount and provides a clear switching logic that can be directly used in many applications. The metallic lever ensures long service life, even with frequent use. The solder terminals enable a secure connection that remains stable even under mechanical stress.

The switch is delivered in a single plastic package classified as bulk packaging.
