IEEE-library form of four-point current measurement selector: this representation identifies selection among four current-measurement points.

## In plain English

### What does ANSI/IEEE Four-point current measurement selector form mean?

This reference locates four-point current measurement selector in Autodesk's IEEE-oriented miscellaneous switches family. This representation identifies selection among four current-measurement points. The additional measurement point expands the selected current-input circuits while retaining a common meter. Each position therefore needs an unambiguous circuit identity. The public library uses HSW1S95 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.

### A simple example

Read the operating mechanism and the contact reference state together. Cross-reference every associated contact to the same device and show which movement, signal or reset changes its condition; the symbol alone does not establish the complete switching sequence.

### What the drawings help you do

Provide all four measurement references and the actual terminal scheme. A voltage selector with the same number of positions is not an interchangeable current-measurement switch. Provide the complete selected switch connection and measurement-point table. The additional point is a circuit interface difference, not merely another drawing orientation. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.

### This particular reference

IEEE-library form of four-point current measurement selector: this representation identifies selection among four current-measurement points. The additional point is a circuit interface difference, not merely another drawing orientation.

### Terms

- Normally open / normally closed: The contact state in the normal condition defined for the drawing.
- Terminal: An identified point where a conductor connects.
- Signal: Electrical information passed between devices, rather than necessarily the main power supply.
