FSW-0492
This is a normally closed pressure switch designed for Mack heavy-duty trucks to monitor oil or air pressure. It sends a signal to the dash warning light or gauge when pressure drops below a safe threshold, alerting the driver. It is commonly replaced when the warning indicator stays on, the switch fails to close, or during preventive maintenance. Directly replaces Mack OEM part numbers 1MR3583M and 25171211.
Multiple-application switch for Mack trucks. Verify exact model, switch location, and pressure rating before ordering.
