- triple pole switch
- double pole switch
- can be any of these
Answer
double pole switch
Reason — A double pole switch is a type of electrical switch that has two separate sets of contacts that can control two separate circuits simultaneously. It disconnects both the live and neutral wires when it is turned off, providing additional safety by ensuring complete isolation from the power source.
