Shockbox SB28-00-400 - Fuel Pressure Test Switch Box BeechJet 400 Series (RJ-1 & After)

The Shockbox SB28-00-400 - Fuel Pressure Test Switch Box is a bench and aircraft-interface tester for fuel pressure switch circuits. It provides a convenient way to simulate fuel pressure conditions and exercise fuel pressure switches and warning circuits, verifying that indications, annunciators, and system logic respond correctly in accordance with the applicable maintenance procedures.

This box is aimed at aviation maintenance organizations responsible for turbine and turboprop fuel systems, but its design is equally applicable to other vehicles and industrial machinery where fuel pressure switches provide critical safety and status information. By centralizing control and measurement of these circuits, the SB28-00-400 simplifies troubleshooting and reduces the need for ad-hoc jumper wiring.

Key Features

• Fuel pressure test switch box for exercising fuel pressure switches and related warning circuits.
• Allows simulation of various pressure conditions and monitoring of the corresponding electrical responses.
• Helps verify cockpit and system annunciations for low or abnormal fuel pressure conditions.
• Enclosed in a durable housing for repeated use in aircraft maintenance and test environments.
• Useful for aviation, ground support, and industrial applications that rely on fuel pressure switching for safety or control.
• Supports both troubleshooting and periodic verification of fuel pressure sensing circuits.
