% h9 I! U6 V0 y9 i7 L) ?8 cDoes a push-push mains switch need to be marked to indicate on/off positions?
+ b# F6 H. \$ {6 [Rationale:
See question.
% c; \; p$ w7 N  \9 u" YDecision:
A push-push mains switch for stationary appliances needs a visual means (e.g. according to
IEC 417 "Graphical symbols for use on equipment") or a lamp to indicate clearly whether
the switch is in the on/off position. The marking should be on or near the switch.
