Master Appliance 845 Switch Accessory
The Master Appliance 845 is a pneumatic switch accessory built from aluminium. It serves as a direct replacement component for compatible heat tool assemblies. This part suits technicians maintaining existing equipment rather than builders specifying new systems. It is not for operators needing a complete tool or a different actuation method.
Compatibility Limited To Listed Part Numbers
Practical use is confined to the manufacturer part numbers AH-301, AH-302, AH-501, AH-502, AH-751 and AH-752. Cross-reference Grainger numbers 1YMJ9, 4Z717, 4Z718, 5PYR0, 5PYR1 and 5PYR2 confirm fitment. No other models are supported by the supplied data. Buyers must verify their exact part number before ordering.
Aluminium Body For Workshop Durability
The aluminium construction resists corrosion and mechanical wear in daily shop environments. As a standalone switch component, it mounts inside the host tool housing using the original fasteners. No additional connectors or fittings are included in the package. Installers should plan for disassembly of the parent unit to complete the repair.
