The Walter 48C103 was a standard electrical switch component used in various high-performance power tools manufactured by Walter Surface Technologies. As part of the manufacturer's continuous improvement and lifecycle management, this specific SKU has been discontinued and officially superseded by part number 48C162. This transition ensures that maintenance teams and repair technicians have access to the most current component revisions, which often include minor design enhancements for better durability or electrical contact reliability.
Switches in industrial power tools, such as angle grinders and linear finishers, are subject to high mechanical stress and electrical arcing. Over time, the internal contacts can wear down, or dust ingress can impede the mechanism. The 48C103 was the original specification for several models. When sourcing a replacement today, it is critical to order the 48C162, as it is the designated functional equivalent provided by Walter. Installing the correct OEM switch is vital for maintaining the tool's safety features, including proper cut-off functionality and prevention of accidental startups.
If you are servicing a tool that lists 48C103 in its parts diagram, you can confidently use the 48C162 as the direct replacement. No significant modifications to the tool housing or wiring harness are typically required, as the form factor remains consistent with the original design specifications. Always ensure the power tool is completely disconnected from any power source before attempting to open the housing or replace internal electrical components.
When replacing a faulty switch, it is also recommended to inspect the carbon brushes and the power cord for signs of wear. Often, intermittent power issues attributed to a switch can also be related to worn brushes. Using genuine Walter parts like the 48C162 ensures that the tool operates within its rated amperage and duty cycle, preserving the longevity of the motor and the safety of the operator.
