Question

For the connection of current-carrying circuit conductors, a dpst switch has ___ screw terminals?

1) two
2) four
3) six
4) eight

Answer 1

A DPST switch has four screw terminals, enabling the control of two separate circuits simultaneously through one operating mechanism.

Step-by-step explanation:

For the connection of current-carrying circuit conductors, a DPST (Double Pole Single Throw) switch has four screw terminals. This type of switch can control two separate circuits at the same time but is operated by a single mechanism. The DPST switch has a pair of terminals for each circuit, which allows for the connection or disconnection of two lines or poles at the same time from a common power source.
