Connects or disconnects an analogue signal path under its documented digital control.

## What it represents

Connects or disconnects an analogue signal path under its documented digital control.
On a schematic, identify the two signal terminals, supply rails and control active level and trace the switched analogue path and its reference limits. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
Bilateral signal routing does not imply unrestricted voltage, current or galvanic isolation.
The preview is an independently drawn educational functional reference. Add the selected component’s actual power pins, terminal numbers, timing or analogue reference details when producing a construction drawing.

## How to read it

- Identify the two signal terminals, supply rails and control active level.
- Trace the switched analogue path and its reference limits.

## Information to show or reference

- Label the two signal terminals, supply rails and control active level.
- Cross-reference the switched analogue path and its reference limits.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.

## Important distinction

Bilateral signal routing does not imply unrestricted voltage, current or galvanic isolation.

## Facts

- Common schematic mnemonic: A-SW — descriptive only; project/device documentation defines reference designations.
- Terminal / interface focus: The two signal terminals, supply rails and control active level
- Artwork scope: Original educational functional/circuit reference; not a selected product pinout.
