Looking for a counterexample

Hi all,

I am trying to find a counterexample for the following
proposition (which is false):

Suppose that we have a sequence (f_n: K -> R^q) (where K is a
compact subset of some euclidean space R^n) of continuous functions and this
sequence converges uniformly to a function f: K -> R^q such that f is an
imbedding of K. Then for n large enough, f_n is an imbedding

Does anyone know of a counterexample in which K is a compact n-
cell ??

Thanks in advance...

Greetings.
