CHANGE REQUEST
Request identity number:
C00204
Applies to:
S01868
Type of request:
Technically new
Request status level:
Resolved
Proposal:
Introduce a new symbol for combined switch type: two-way single pole and single pole On-Off switch
Reason:
In IEC 60617 DB there is no symbol for installation diagrams for presenting concept combined-switch. One example for such device is device which combines functions of two-way single pole and single pole on-off switch. Keep in mind such a device will be installed single mounting box for switches. Combined-switches are commonly used in building installation, but it is not trivial how to construct a symbol for presenting device which has a two or even more independent actuators. Therefore this concept should have internationally standardized graphical symbol suitable for installation diagrams.
FI NC propose to standardize a new symbol for combined-switch. Such a device combines functions of two-way single pole and single pole on-off switch. New symbol shall be used for document kind “Installation diagrams”. In our proposal we take symbol S00471 as a base and add one extra line to represent object has two independent actuators one for On-Off switch and one for two-way single pole switch.

General comments:
Comments at evaluation:
JP(HIKE): Please provide us an example of use in order to evaluate.
DE(RESC): We support the suggestion of the JP NC that it would be very helpful for evaluation if you add an example.
AT(WGAS): AT NC gives the following comments: This symbol is a combination of existing symbols therefore is no need for a new symbol. The lines of this symbol should be turned in a "V"-position like S00470.
--------------------------------------------------
Secretary comment: The symbol cannot be evaluated in this form as commented by the NCs. I understand the JP comment as a request of a comparison between the "installation symbol" with the corresponding "electric diagram symbol". A document is under preparation listing the different "switch symbols" for installation and showing corresponding sysmbols. This document will be added to a new Change request referring to this CR and other not yet validated CRs.
------------------------------------------------
Secretary comment: C00204 will be put "on hold" waiting for the result of C00206. The continuation will be dependant on this CR.
-------------------------------------------------Secretary comment: The voting on C00206 resulted in a decision to go to Extended Database Procedure which also includes this CR.
Comments at validation:
The extended procedure was closed with an approved CDV. See 3/1099/CDV and 3/1118/RVC.
The extended procedure resulted in a changed shape
