Abstract
A submersible pump such as a sump pump or sewage pump has a handle which also serves to provide electrical connections and an oil port. The handle has two barrels which extend through the top of the pump casing and receive nuts which secure the handle on the pump. O-rings are provided beneath flanges on the barrels for sealing purposes. Retainers for the O-rings hold them beneath the flanges. One barrel has electrical terminal pins molded into it. A power cord can be connected with the pins by inserting a plug on the cord into a socket on the barrel. Within the pump casing, the terminal pins are connected with wiring for the motor. An external float switch controls the on and off conditions of the motor. The second barrel provides an oil passage which may be closed by a removable threaded plug.
