Knife Switch Board and the Light and Buzzer Board
The knife switch board functions as a power switch. It is a clear way
to demonstrate what happens when a power switch is turned on/
off. The knife switch can be used with the red or black lead, but you
will use the black lead. For these instructions, you will wire the knife
switch to the light and buzzer board.
1. Make sure the knife switch is open. Use a black lead to connect the
(-) terminal of the battery to a terminal on the knife switch.
2. Use a black lead to connect the other terminal on the knife switch
to the (-) terminal of the light.
3. Use a red lead to connect the (+) terminal of the second battery to
the + terminal of the light (Figure 8).
4. To turn the light on, close the knife switch.
5. Repeat Steps 1-4 for the buzzer.
