Littelfuse Low Air Pressure Indicator Buzzer

The Littelfuse Low Air Pressure Indicator Buzzer is an audible alarm designed to signal changes in system pressure—including low air conditions that affect braking systems—rather than a generic buzzer that makes noise with any input. It’s built to work with standard 12-volt vehicle electrical systems and provides a clear audible alert when its connected switch or sensor detects pressure below a safe threshold, helping tie the warning directly to the air-brake system’s status. Littelfuse buzzer devices are electromechanical units intended for use with a variety of pressure or temperature switches, including low air pressure monitoring circuits often found in heavy-duty trucks and trailers. The compact form and mounting arrangement suit dash or panel locations where space is limited but visibility and audibility remain important. The Littelfuse 249901 gives you a purpose-specific warning buzzer that aligns with low-pressure brake monitoring applications rather than a general-purpose noise device.
