Main On/Off Power Switch for various NAD Amp Models

[tiefbassuebertr]

I need follow power switch (double switch) for replace by NAD integrated amp model 3130; one half for mains switch ON (active = Power ON, passive = Power-Off) and the other half for switch off the connection between R516 (390R) and neg pole of C520, 47uF at the same time (Active = off, Passive = on).
In my NAD model 3130 this "ON" function after performed "switch-off" serves to avoid buzzing-, bump and noise effects (through switch off the mute jFETs Q303/304, type J111) by the preamplifier output signal at the pre-out female rear cynch plugs so as the power amp input.

Where I can order such kind of doubleswitch - the NAD order code (mentioned in the service manual of 3130) are follow:
L432Y034H01 and L432Y035H01

By a wide range of other NAD models so as other brands this kind of switch is also in use. Thus it must be an universal device and not a custom made device - so I think. But I am not absolutely sure

Thank you very much for appropriate hints about brands and delivery sources so as the the popular name in colloquial english for this kind of "Power-ON" main switch.
