the extra current for at least a reasonable time.
I am sure it can. We are talking about logic-level signals here, I would
guess the currents involved are measured in 10's of mA at most. No normal
switch is going to have problems with that.
If you have the
information, can you describe the
circuits that were soldered and the size of the
resistors? In addition, would Tony (I guess this
is twice that I have taken your name in vain -
I apologize) be able to suggest the additional
circuits needed to add the green and orange
LEDs to show the same status that the 6 button
front panel for the BA23 shows?
Assumeing the circuits on Pete's web page are accurate, it should be
quite easy to do this.
Are the 4-button and 6-button panels base o nthe same PCB, with the
former being partially populated, or are they different PCBs?
