Detailed Description

This rugged rotary switch was manufactured by Electro Switch Corporation of Weymouth, Massachusetts - a company long recognized for building industrial-grade and military-spec switches for power, control, and instrumentation systems.

The M15291 / 6-006 is a multi-deck, detent-action rotary switch rated for 30A at 500VAC or 30A at 250VDC, designed to handle high-current loads in demanding environments. Its detented action gives a solid “click” feel at each position, ensuring positive contact and precise operation.

The gray stacked decks function as independent switching sections, allowing multiple circuits to be controlled simultaneously. Heavy brass and copper contacts provide excellent conductivity and reliability, while the zinc-plated steel housing offers outstanding durability. The black handle rotates smoothly, ideal for use as a selector or power switch.

This model follows design principles of MIL-S-15291, a military specification for naval and aerospace rotary switches - reflecting the same focus on ruggedness, long life, and resistance to vibration or shock.

Common uses include:
• Industrial control panels and test benches
• Motor and power source selection
• Instrumentation mode or range switching
• Heavy-duty machinery and utility systems
