Formative 1.5 The Switch

What is a key feature of all mechanical switches?

• They have only one contact point.

• They are always made of plastic.

• They have at least two contact points.

• They do not conduct electricity.

What does a Single-Pole, Single-Throw (SPST) switch do in the "on" position?

• Opens the circuit.

• Closes the circuit.

• Reverses the current.

• Increases voltage.

Which type of switch is commonly used in computers?

• Knife switch

• Toggle switch

• Electronic switch

• Rocker switch

What is the function of a Double-Pole Double-Throw (DPDT) switch?

• It increases voltage.

• It reverses the direction of current.

• It decreases resistance.

• It opens the circuit.

How many contact points does a Single-Pole Double-Throw (SPDT) switch have?

• Two

• Three

• Four

• Six

What happens when a "normally off" momentary switch is pressed?

• The circuit remains open.

• The circuit closes temporarily.

• The circuit reverses direction.

• The circuit increases voltage.

What is a characteristic of a Double-Pole Single-Throw (DPST) switch?

• It has two contact points.

• It connects two separate circuits.

• It is used for reversing current.

• It is always "on."

What is the purpose of an insulated handle on a switch?

• To increase current flow.

• To prevent electric shock.

• To decrease resistance.

• To enhance conductivity.

Which switch type is used for an "either circuit 1 or circuit 2" situation?

• SPST

• SPDT

• DPST

• DPDT

What is a feature of a "normally on" momentary switch?

• It keeps the circuit open until pressed.

• It keeps the circuit closed until pressed.

• It reverses the current when pressed.

• It increases voltage when pressed.
