Abstract: A switching device for submersed sump pump. The switching device employs an internal logic circuit inside a housing having a metallic member extending therefrom for mounting. The member is adapted to engage with the curved surface of a hose and hose clamp engaged to the sump pump. The member is engaged to the electrical ground to communicate a reference ground to the fluid in the sump to allow an impedance sensor to discern the fluid level and cause the logic circuit to energize or de-energize the sump pump.
