A hardware switch for use with hypervisors and blade servers is disclosed. The plunger component is configured so as to be adjacent to the piston component and to have a break-off point for the purpose of dividing the plunger component into a removable component and a component rigidly connected to the piston component. An inner directional ring formed within the eyeball fitting cooperates with the outer openings to enable the direction of water jets at non-perpendicular angles to the outer eyeball surface.
