ANSI/IEEE Foot-operated switch form
IEEE-library form of foot-operated switch: a foot-operated switch uses a pedal mechanism to change an electrical contact.
In plain English
What does ANSI/IEEE Foot-operated switch form mean?
This reference locates foot-operated switch in Autodesk's IEEE-oriented miscellaneous switches family. A foot-operated switch uses a pedal mechanism to change an electrical contact. Its schematic should state the contact state and whether the operator is momentary or retained. The public library uses HFT11 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
Identify the pedal's return action and any guard shown by the equipment specification. Foot operation describes the operator, not the safety category of the circuit. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.

How to read it
- Identify the pedal's return action and any guard shown by the equipment specification.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- State contact type
- Reference return mechanism
- Identify connected control function
A distinction that matters
Foot actuation describes the operator, not the safety category of the circuit.
