3-Position Switch

Educational Corner:

Some switches can be very complex, switching groups of parts on or off at once.

Electric Paths

1A

1A

Push the press switch (S2) to turn on the right lamp and
use the slide switches (S5) to control the other parts. The
meter measures the circuit current.

Operation

This circuit uses both slide switches to simulate a larger
switch controlling many things.

This circuit has 3 lamps and 1 motor. When the press switch
is pushed, 2 of these will always be on - you can’t set the
slide switches to control more or less.

Description

Build the circuit and set the meter (M5) to the 1A scale.

Assembly

Snappy says: watch how the right lamp gets
dimmer when the motor is turned on. The
batteries can’t supply as much current as the
motor wants, so the voltage drops a little.
