Plug34.dat and related parts discussion

[Rene Rechthaler]

as I began to explain on the part itself, here is my suggestion:
4707: base part (just plastic, no metal)
4707c01-c03: body (base+metal+cover)
4707c0Xp0X: assemblies with (printed) keys ->p00 is unpatterned
example: 4707c01p01: 3 hole cover with the keys for the switches
c01p02: decoupler
c01p03: circle arrows
c02p01: barrier
c03p01: signal
c01p00: 3 holes and unpatterned keys
