I read in sci.electronics.design that Spehro Pefhany <speff@interlog.com> wrote (in <c52kvuc8sut17acevom3dimg06i7d1ffn0@4ax.c om>) about 'Best way to power array of LEDs?', on Fri, 13 Dec 2002: >They have a nasty habit of using nickel-plated PCBs as the stator part >of the switches in cheap DMMs. Yes.
