DESCRIPTION
Built for subsea control applications, the Subsea Embedded Push Button Switch delivers reliable tactile feedback and water-resistant operation without interfering with sensitive electronic systems. Its non-magnetic stainless steel construction is specifically suited for use near sonar, compasses, or other devices affected by magnetic interference.
The switch operates in a momentary (tap) configuration — conduction is only active while pressed — with no self-latching function. Its internal components are pressure-sealed, verified through 480-hour testing at 1.2 MPa and over 30,000 actuation cycles, ensuring long-term durability and consistent performance under pressure.
Intended for shallow subsea or air environments, the switch supports electrical signals up to 50 mA at 12 V DC and is best used for triggering control signals or interface inputs. Installation requires attention to O-ring surface finish and a chamfered entry to ensure sealing integrity.
Maintenance is minimal, though the device may require rinsing after extended use in murky or saline water to remove buildup from tight crevices.
Compatible with: Toggle Relay Control Module
Sold Separately
This switch is fully compatible with the Toggle Relay Control Module, which allows a momentary tap to toggle power on or off to connected devices.
Pairing this switch with the relay module adds self-latching behavior, long-press shutdown, and debounce protection—ideal for controlling subsea lights, pumps, or solenoids using a compact mechanical interface.

Mounting Hole Dimensions
Dimension drawing provided below.
Please note the following installation requirements:
- An introduction chamfer of 1.5 × 20° is strictly required.
- The O-ring contact surface must be smooth and free from scratches.
- The O-ring should be coated with grease to ensure easy installation.
After using it in murky waters for a while, I feel some resistance when tapping the button. Is this normal?
Yes, this is normal. Small particles, salt crystals, or other impurities may enter crevices around the button. Soaking the switch in warm water and pressing it repeatedly can help clear out debris and restore smooth operation.
Can this switch handle high-current power sources?
No, this switch is not designed for high-current applications. It should be used only for low-power signal control.
Can you provide an electrical schematic for the switch?
A dedicated schematic is not required. It functions as a simple physical on-off switch with two leads—no internal electronics are involved.
Can this switch be used in shallow water or in the air?
Yes, the switch is suitable for both air and underwater use, rated for depths from 0 to 100 meters.
