SWITCH - KEY (Mitsubishi MB191633003)

MB191633003: A damaged key switch can prevent the ignition circuit from completing, leaving the equipment unable to start. During inspection, a key switch may show worn internal contacts that cause intermittent electrical connection. The switch's mechanical function is to rotate a tumbler assembly that aligns internal contacts to close the circuit. Keeping a key switch in sound condition helps avoid unexpected shutdowns during operation. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB191633003. Verify the serial number or application, then call (562) 693-7748.
