IEEE / ANSI

ANSI/IEEE Self-operating thermal switch form

This reference locates self-operating thermal switch in Autodesk's IEEE-oriented pressure and temperature switches family. A self-operating thermal switch responds directly to its thermal condition rather than through a separate powered relay input. Its contact and reset behaviour are device-specific. The public library uses HTS12S59C for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.

Thermal Switch Normally Closed, Self-operating. Autodesk IEEE Symbol Preview: Pressure and Temperature Switches, block HTS12S59C. Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier.

A distinction that matters

A self-operating thermal switch is not the same as a powered temperature monitoring relay.
