Final answer:
A single-pole, double-throw switch (SPDT) has one pole and two possible positions for the throw.
Step-by-step explanation:
A single-pole, double-throw switch (SPDT) has one pole and two possible positions for the throw. The pole refers to the common terminal of the switch, while the throw refers to the number of terminals or contacts that the switch can connect to. In the case of an SPDT switch, there are two possible positions for the throw, allowing the switch to connect with two different terminals or circuits.
