I'm wondering what the 2 way switch is for that triggers the pump to empty out the water basin
A two-way switch is a type of switch that allows you to control a circuit with two separate locations. It is often used to control lights, fans, or other electrical devices from two different locations.
A two-way switch that triggers a pump to empty out a water basin is likely part of a sump pump system. A sump pump is a device that is installed in a pit or basin in the basement or crawl space of a home. The pit is designed to collect water that may seep into the basement. The sump pump then pumps the collected water out of the basement and away from the home.
The two-way switch you are referring to is likely a switch that is installed in two separate locations. One location would be near the sump pump, and the other location would be in a convenient location for the homeowner, such as near the electrical panel or in a living area. The switch allows the homeowner to turn the sump pump on or off from either location.
It could also be a two-way switch that controls the water level in the basin, when the level reaches a certain point, the switch triggers the pump to turn on and empty the water out.
It is important to consult with a professional electrician or a plumber if you have any doubts about the proper installation or operation of the sump pump and its switches.
