The Piranha range of safety switches

Piranha is our trade name for the range of 400 amp DC safety/monitor and control switches we manufacture. These units are designed to sit in-between the power source and the diver, providing a safe method of isolating current and voltage for the diver, or operator.

1 Image of Piranha switch - utility model Utility case
2 Image of Piranha switch - large model Steel wall mounted (large)
3 Image of Piranha switch - junior model Junior (steel portable or wall mounted)

The utility case and large wall mounded units are fitted with amp and volt meters as standard thereby, allowing welding parameters to be monitored and/or recorded and the units also provides a useful means of checking working efficiency of the power source.

Although initially designed for welding/cutting underwater, the devices are equally well suited for situations where close control of thermal operations in hazardous areas is required.
