ANSI/IEEE Automatic mechanical-return indication form
IEEE-library form of automatic mechanical-return indication: this indication identifies the automatic return behaviour of a mechanical control relationship.
In plain English
What does ANSI/IEEE Automatic mechanical-return indication form mean?
This reference locates automatic mechanical-return indication in Autodesk's IEEE-oriented mechanical controls family. This indication identifies the automatic return behaviour of a mechanical control relationship. The public library uses Q021207 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
Show the rest position and the force or condition removed to allow return. Mechanical return behaviour is separate from electrical contact normal state. Show the rest position and the force or condition removed to allow return. Mechanical return behaviour is separate from electrical contact normal state. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.

- Normally open / normally closed
- The contact state in the normal condition defined for the drawing.
- Signal
- Electrical information passed between devices, rather than necessarily the main power supply.
- Rating
- A value stating the conditions for which equipment is specified.

How to read it
- Show the rest position and the force or condition removed to allow return.
- Mechanical return behaviour is separate from electrical contact normal state.
Information to show or reference
- Identify the associated device, circuit or diagram boundary.
- Show the rest position and the force or condition removed to allow return.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.
A distinction that matters
Mechanical return behaviour is separate from electrical contact normal state.
