Industrial equipment - Germany

Rare Siemens & Halske industrial cast-iron doorbell, German industrial design. A magnificent piece of German electrical engineering from the mid-20th century. This wall-mounted dual-coil bell is a classic example of rugged durability, designed to last for decades in industrial environments or complex signaling systems.
Material: Cast-iron gongs, which provide a metallic, resonant, nostalgic sound.
Rare mechanism: Includes an original 3-position switch (left/center/right), a rarely seen feature that allowed switching between signaling modes or silencing the device.
