The 2-Deck Multi-Position Rotary Switch is an essential component for engineers and hobbyists requiring synchronized control over multiple electrical circuits. This professional-grade selector features a dual-wafer (2-deck) design, allowing you to switch two independent circuit layers simultaneously with a single turn of the dial. Whether you are selecting audio channels, adjusting industrial machinery modes, or managing power distribution, this switch provides the mechanical reliability and electrical precision needed for high-performance applications.
Synchronized Dual-Deck Control: Two stacked wafers enable complex multi-pole switching, perfect for stereo audio or redundant safety signals.
High-Conductivity Silver Contacts: Designed for low contact resistance and long-lasting signal integrity through thousands of rotations.
Tactile Indexed Detents: Provides a firm, satisfying "click" for each position, ensuring the operator can feel the selection without visual aid.
Industrial-Grade Shaft: Features a rugged metal shaft with a flat D-shape profile to prevent knob slippage during high-torque operation.
Heat-Resistant Phenolic Base: The high-strength insulating wafers provide excellent electrical separation and thermal stability.
This 2-Deck Rotary Selector is a top choice for:
Professional Audio Gear: Signal band switching, channel selection, and impedance matching in mixers and amplifiers.
Industrial Automation: Toggling between operation modes (Auto/Manual/Setup) or managing multi-stage power sequences.
Communication Equipment: Frequency range and antenna selection in radio and broadcasting hardware.
Test & Measurement Units: Precision range selection for laboratory multimeters and diagnostic tools.
Terminal Type: Solder Lugs for permanent, high-integrity connections.
Mounting Style: Standard Panel Mount with threaded bushing and hex nut.
Can I use one deck for AC and the other for DC?
Yes. Because the decks are physically and electrically isolated from each other, you can use the stacked design to manage two completely different types of signals simultaneously.
What is the advantage of a D-shaft over a round shaft?
The D-shaft has a flat side that aligns with the set screw or internal shape of the knob, ensuring the knob pointer always accurately reflects the switch position without spinning freely.
How many positions are available?
This varies by model, but standard industrial rotary switches often come in 6, 8, or 12-position variants. Many also feature an adjustable stop ring to limit the rotation to your specific needs.
