Subsea M10 Rotary On/Off Switch

Constructed from either black anodized aluminum or corrosion-resistant stainless steel, the switch supports up to 0.5A at 24VDC or 0.2A at 48VDC and integrates easily with low-power systems. It includes a clearly marked knob for position status and a protective circular step to prevent installation damage.

The switch is compatible with the MOS Low-Side Switch Board, allowing users to safely control higher-current loads or inductive devices without overstressing the switch contacts.

An alternative compact version is also available as the Subsea M8 Rotary On/Off Switch, offered exclusively in aluminum anodized construction for space-constrained builds.

The Subsea M10 Rotary On/Off Switch provides a robust and intuitive latching control solution for underwater applications. With a positive two-position rotary mechanism, it allows operators to manually toggle power or signal pathways inside a sealed enclosure, eliminating the need to open housings for access. Each position is clearly defined with an audible click and tactile stop, ensuring reliable feedback even while submerged.

This switch is depth-rated to 1,000 meters and is available in both 316 stainless steel and black anodized aluminum for flexibility across corrosion-sensitive or weight-conscious projects. It operates up to 0.5A at 24VDC or 0.2A at 48VDC, making it suitable for low-power switching tasks. For higher-power circuits, the switch can be safely paired with external control modules such as the MOS Low-Side Switch Board to handle heavier loads and inductive devices.

Designed with subsea reliability in mind, the switch features a non-continuous wrench socket with a protective circular step to reduce installation-related surface damage. For tight mounting conditions, the head includes a semi-circular groove that can be rotated using snap ring pliers, avoiding the need for custom tools. Secure fastening is recommended using anti-slip washers and Loctite threadlocker, taking care to prevent contamination of the gasket interface.

For projects with tighter space constraints, a smaller format alternative is available as the Subsea M8 Rotary On/Off Switch, offered exclusively in aluminum anodized construction. Both models offer long service life and are ideal for underwater vehicles, control pods, lighting systems, and instrumentation panels.
