The Craftsman 42-278 pressure switch is an essential component for the efficient operation of the 40/60 jet submersible pumps (model numbers 42278 and 422782) manufactured by Craftsman. This pressure switch is meticulously designed to ensure reliable and automatic pump shut-off once the desired pressure is reached.
The pressure switch features a durable, corrosion-resistant housing, which makes it well-suited for use in water applications. Its compact size enables easy installation, typically mounted on the pump discharge pipe or the pressure line. The switch is equipped with a sensitive diaphragm that accurately measures the pressure level.
When the pump is in operation, and the pressure rises above the preset level, the switch will activate the contacts, causing the pump to shut off automatically. This feature not only protects the pump from damage caused by excessive pressure but also conserves energy by preventing the pump from running unnecessarily.
The Craftsman 42-278 pressure switch is designed for versatile use, accommodating a wide range of pressure levels. It can be set to switch off at pressures between 2.5 and 6.5 psi, providing flexibility to cater to various applications.
The switch comes fully assembled and is ready for installation, eliminating the need for additional components. It is compatible with both the 42278 and 422782 Craftsman 40/60 jet submersible pumps, offering a reliable and convenient solution for managing water pump pressure.
In summary, the Craftsman 42-278 pressure switch is a must-have accessory for those using Craftsman 40/60 jet submersible pumps. Its rugged construction, pressure sensitivity, and easy installation make it a valuable tool for ensuring the optimal performance and longevity of the pump system.
