The push buttons, both the larger 4 leaded ones and the
small 2 leaded ones, are intended for PCB mounting and won’t plug into a
breadboard without modification.
You will need to flatten out the “kinked” looking part of
the lead so that it points straight down from the switch body. I used a pair of small needle nose pliers but
you could use tweezers if that’s what you have. The switch will then plug into the breadboard
with only a bit of force. Be sure to
push more or less straight down with only a bit of wiggling as the leads will
break off if flexed to many times. I
pulled the colored caps off to make installation easier and let the kid put the
correct color on as instructed during play.
The large push buttons have 4 leads. They are double pole, single throw
(DPST). This means that there are 2
switches in the housing. Pressing the
button connects the leads that are on each side together but not to the leads
on the other side. If you follow the
engraved layout exactly, you will have the large push buttons installed
correctly and the jumper wires will be in line with the switch leads.
The small push buttons are single pole, single throw
(SPST). They only have one switch. You must take care to put the jumper wires in
the same row as the lead when connecting them.
The slide switch is a single pole double throw (SPDT). The center lead is common. The slider shows which of the outside leads
will be connected to the center one. You
will want one jumper to be in the same row as the center lead and one jumper in
the same row as one of the outside leads.
Take a look at the big breadboard. See the 2 outer columns on each side? They are labeled with a + and a -. These are the power rails. They run the full length of the
breadboard. We won’t be using these in the
Piper so let’s ignore them. Notice that
the rest of the breadboard is labeled with letters and numbers. The numbers are the rows, the letters are connections
in each row. In row 1, a, b, c, d, and e
are connected together but not to any other point on the breadboard. Also in row 1, f, g, h, I and j are connected
together but not to any other point on the breadboard. The small breadboards are the same but do not
have the power rails.
When we assembled the big breadboard, we ended up with the black
button in rows 2 and 4, columns d and g.
This means that we can put a jumper wire in row 2, a, b or c and another
jumper wire in row 4, a, b or c.
With the small pushbuttons and the slide switches, make sure
that each switch lead goes into its own row and that the jumper wire go into a
row that lines up with a switch lead and you should be OK.
