41. OR Gate Controlling Parallel Electrical Appliances
Build the circuit above. Press either the press switch (61) OR the switch (62) to turn on the lamp (76) and the motor
(95). If you want to turn off the lamp (76) or turn off the motor (95), both the press switch (61) and the switch (62) must
be OFF. You might think this type of circuit could be used to have multiple switches in a room control the same device(s).
However, this type of circuit is not ideal because the switches do not toggle with each other. In your house, if you pushed
the switch (62) ON to turn on your lights, then if you pressed the press switch (61) you would want your lights to go OFF.
Your house uses three-way switches to do this, not the circuit above.
