Type of request:
Technical modification
Request status level:
Resolved
Proposal:
Introduce a general block symbol for a complex switch.
The proposed symbol S01454 combines the already standardised symbols for a switch S00227 with the qualifying symbol for a complex-function element IEC 60617-12-54-01 (Greek upper-case letter "phi", symbol S01731.)
The other symbols listed above have been suggested to be withdrawn by 3/596A/CDV. If the proposed symbol S01454 is approved then those symbols should be provided with a "Replaced by" link to this one.
Reason:
This proposal follows from the comments provided in document 3/635/RVC, Report on the voting on document 3/596A/CDV.
TC3 decided at its meeting in Prague 2002 that the proposed symbol should be circulated for evaluation and validation before circulation of the FDIS based on 3/596A/CDV, proposing the withdrawal of a number more specific construction-based symbols for complex switches.

Comments at validation:
Circulated for validation 2002-12-22.
FI(TAVI): For readability I propose slightly bigger font for Greek upper-case letter "phi". In addition I propose new qualifying symbol Greek upper-case letter "phi" for "complex-function". This could be used in other symbols like e.g for complex measuring relays.
Voting at validation:
AT(WGAS): Yes to symbol S01454. Yes to withdraw the symbols S00273; S00274; S00275; S00276; S00277.
DE(RESC): YES to the proposal

NO(ES): Yes to the proposal
FR (TOPC): Yes to the prposal
Conclusion by the Secretary 2003-03-03: The proposal is approved and will be implemented. The size letter phi will be slightly inreased in size.
A new change request will be issued proposing the capital letter phi as a general symbol for complex function.
