Float Switch: Narrow-Angle, Normally Open (Pump Down), 120/230V AC, 5 A, 2-Wire, 10MPCNO

These switches are activated by a float attached to the pump by a flexible tether that can be adjusted so the pump starts and stops automatically at preset levels. They require more space than vertical float switches since the tether moves in an arc as the water level rises and falls in the sump basin.
