An activation device for use with a sump or other type pump is provided. The device includes a switched outlet into which the electrical plug of a pump is plugged. The switched outlet is connected to a switching means that is activated by conditions related to the rising and falling of water in the area about a pump, such as the sump of a home or other building. The activation means has an electrical micro-switch associated with a lever attached to a float rod and float; biasing means, locking the switch into an on position until the occurrence of a predetermined event, are provided. As the float rises the switch is activated allowing electricity to flow to the pump. The biasing means permits the pump to continue to operate as the water level in the sump falls. When the water level falls to a desired low level, the activation means is triggered to cut electricity off to the pump, and return to a standby state.
