Project 160
Spinning Reed Switch
Assembly :
1. Place the base grid supports and the parts on base grid A.
2. Install the gear insert and large gear on the orange motor.
3. Place parts on grids B, then install grid B onto base grid supports
on grid A.
4. Mount the reed switch (S9) to the 3D snaps, and attach the
push switch (S2) opposite side as shown. Add the small gear.
5. Mount the switch assembly from step 4 between the 1-snap
wires on grids A & B, as shown.
6. Lay the magnet on the 2-snap wires as shown.
Turn on the slide switch (S1); the gears rotate the switch assembly.
When the reed switch moves past the magnet the switch closes and
both LEDs light. If the LEDs don’t light try adjusting the magnet
position, and shift one of the blue jumper wires to the other side of the
LED it connects to. If you have other magnets you can try using
them.

Project 162
Spinning Reed Switch 3
Use the preceding circuit, but replace the blink
red LED (D11) with the clear motor (M4). Attach
the fan to the clear motor.
When the reed switch (S9) passes the magnet
the switch closes, the blue LED (D9) flashes,
and the fan spins.
Use the project 160 circuit, but replace the
blink red LED (D11) with the lamp (L4), move
the blue jumper wire from base grid A location
G3 to G5, and connect the black jumper wire
across base grid A locations G3 and E8.
Turn on the slide switch (S1). The blue LED
(D9) lights. When the reed switch passes the
magnet, the LED and the lamp turn on and off.
Project 163
Spinning Reed Switch 4
Use the preceding circuit, but replace the lamp
(L4) with the clear motor (M4) and attach the fan.
Turn on the slide switch (S1). The fan spins and
the blue LED (D9) lights. When the reed switch
passes the magnet, the LED turns off and the fan
speed up briefly.
Note: If the LED
assembly fit seems tight,
remove this 1-snap wire.
