Pressure Activated Switches

Global Ocean Design - Ocean Innovations - Ocean Innovations

Global Ocean Design Pressure Activated Switches are built around a high reliability gold over silver contact mechanical switch that guarantees “OFF” is off, and “ON” is on. The customer has the option to order the unit to either turn “on” or “off” at depth.

The interior switch current carrying capacity is 250 mA @ 120 V AC or 28 V DC, 125 mA @ 250 V AC. Higher current loads may be controlled using solid state MOSFET. Quiescent current in the “off” position is zero.

The standard pressure activated switches body is built from high tensile strength and corrosion resistant Titanium Grade 5. The switch functions at 2-3 atm pressure differential, and can survive over-pressure to 18,000 psi. Each switch is individually tested for both switching function and pressure tolerance, and comes with a test certificate.

A low activation pressure option triggers at 4-8 psi, and survives over-pressure to 1,850psi (125 atm).

A 6061-T6 body is available for the model G-121 for flat end caps.

Two engineering plastic body PBOF switch designs are also available (G-119, G-154). Contact factory for details.

Pressure activated switches models include:
G-117: In-line on a pigtail with underwater connector
G-120: Ti body for glass housings
G-121: Ti or Aluminum body for flat endcaps
