Side-by-side reference

Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

First referenceCompare with

TS NO

IEEE / ANSI

ANSI/IEEE temperature switch no symbol

The temperature-operated NO form relates a discrete contact to a specified thermal condition. Sensor placement and rising or falling temperature action need annotations beyond the actuation modifier.

Drawing use: Schematic
Application: Control circuits
Reference family: IEEE / ANSI / Manufacturer
Form evidence: Autodesk IEEE-oriented Pressure and Temperature Switches functional form. Autodesk explicitly publishes this block under IEEE Symbol Preview. The counterpart is the matching functional concept; no equivalence of every detailed standard graphic is asserted.

A distinction that matters

A temperature switch is distinct from an RTD or thermocouple measurement input.

TS NO

Symbols

Temperature switch NO

A temperature-operated NO switch changes from open to closed under its specified actuation condition. The drawing must identify the sensed location and temperature direction.

Drawing use: Schematic
Application: Control circuits
Reference family: IEC / Manufacturer

A distinction that matters

A temperature switch provides a discrete contact state; an RTD provides a resistance measurement.
