RE: Requirements for Power On/OFF Switch...US and EU Europe
In North America, you cannot have a mechanical attachment for the plug if that attachment requires the use of a tool to release it. A bracket screwed over the plug would make it permanently connected, and you are not to use flexible cords for permanent connections. The best alternate is a locking outlet. There are NEMA WD-6 locking configurations for all standard non-locking plug types. The NEMA L5-15P is the locking version of the standard three-prong plug. It is not common, but it is available. You can get duplex NEMA L5-15R receptacles that are the same form factor as a standard duplex receptacle. These locking outlets are a twist-lock type. It takes a slight rotation of the plug to lock it into place, but then it is difficult to accidentally knock loose. You can still disconnect it easily when required. Note that it is acceptable to use a bracket to connect the receptacle of a detachable power cord to an appliance inlet on equipment. In this case, you are basically converting a detachable power cord into a non-detachable power cord. These types of brackets are common and will be accepted by an NRTL or electrical inspector. However, the plug end of the cord must still be detachable by hand.

Securing it permantanly and no longer a quick disconnect. Picture the male AC end going to the wall outlet, but screwed in, not just plugged in.

Re: Requirements for Power On/OFF Switch...US and EU Europe
Hello Christine, No violation at all. IEC/EN 60950-1/UL60950-1/CSA C22.2 60950-1 allow the plug on the power supply cord or the appliance coupler to serve as a disconnect. For your info, most swithes on ITE equipment are single pole - they are not double-pole and do not have the 3 mm contact gap to qualify them as a disconnect device to shut off the system for servicing.

RE: Requirements for Power On/OFF Switch...US and EU Europe
Apart from Safety, there is the European EuP Directive. For products within the scope of the EuP and its Implementing Measures on Off mode and Standby, providing a power switch might be the only possible solution for most products to comply with Tier 1, exp. to become mandatory end of 2009.
