SW FUSE
Fused switch
A fused switch combines a switching function with fuse protection.

What it represents
The fused-switch form keeps a fuse protective element associated with a switching path. Read the switch and fuse ratings independently, then follow the device tag to the complete assembly and replacement fuse schedule.
This is a convention-specific lookup based on the publisher's IEEE-labelled preview. The geometry here is independently drawn to explain the connection or operation; it is not a certified reproduction of the standard graphic.
How to read it
- Do not interpret the fuse current as the switch's complete operational rating.
- Read the selected library and the project legend together. A vendor block identifier is meaningful within its named library and is not a universal standard-symbol code.
Information to show or reference
- Identify assembly tag
- Record fuse-link type/rating
- Reference switch duty
A distinction that matters
A combined fused-switch form is different from a bare fuse symbol and from a circuit breaker.
