Is it possible to build a simple circuit where one switch controls all bulbs but small switches control individual bulbs?
What about this:







simulate this circuit &ndash; Schematic created using CircuitLab

The left schematic is as I interpreted from your description.


S1 switches all LEDs on
S2 switches only B2 on
S3 switches only B3 on


The right schematic is if you'd want to control all LEDs separately.


S11 switches all LEDs on
S12 switches only B11 on
S13 switches only B12 on
S14 switches only B13 on
