Kaan,

In a previous life I worked for a Midwest manufacturer of audio equipment ( 
amplifiers, signal processors etc) and we did not CE mark our footswitches. 
 They do not have an "intrinsic" function of their own, so I do not believe 
that they meet the criteria for CE marking.  However, like an add-on in any 
other system, they cannot compromise the safety of EMC performance of the 
unit when they are installed (ie: plugged in).  In this case, you would 
want to run your safety and EMC tests with the footswitch "installed".  You 
can probably expect to see a change in the immunity and emissions profile 
of the unit.  There may not be a great risk in CE marking the switch, other 
than causing confusion.  Hope this helps.

Hello all,      I would like your opinions on this one...I have an audio 
signalprocessor that has been EMC and Safety tested and which bears the 
CEmarking in accordance with the EMC and Low Voltage Directives.  
Thisproduct utilizes 1/4 in. audio jacks for audio signal input/outputs.  
One ofthe options that we provide to the user, as a separate purchasable 
unit,is a passive foot switch that is comprised of a metal box roughly 2 
in. x 4in. x 5 in., a single 1/4 in. jack,  and three single pole-single 
throw on/offswitches (approx. cost is $10.00 US).       My questions are; 1.  
Is this simple foot switch device required to bear the CE marking? Under 
which directives?2.  Does it make sense to CE mark such a passive device, 
considering itssimplicity and the impact of the increased cost to mark the 
device?3.  Is anyone aware of similar passive products that bear, or don't 
bear,CE marking?4.   What are the potential risks associated with not CE 
marking thissimple device if CE marking is/is not required?     I realize 
that the potential answers to my first and secondquestions may be 
contradictory, but I would appreciate your opinionsregarding this 
matter.Thank you, Kaan L. GregersenCompliance Engineering ManagerDigiTech
