Abstract
A sump pump motor switch assembly for a sump pump including a motor casing and an end shield, includes a switch assembly and a housing mounted to the end shield. A cam actuator is connected to the housing and a sump pump actuation switch is mounted with the cam actuator. A motor actuation switch is also mounted with the cam actuator body. The sump actuation switch and the motor actuation switch are snap action switches that are simultaneously actuated by the cam actuator. The switch assembly includes a snap fitting assembly configured to fit into a receiving retainer within the motor casing.
Claims29
A switch assembly for a sump pump including a motor casing and an end shield, said switch assembly comprising:
- a housing mounted to the end shield;
- a cam actuator connected to said housing, said cam actuator comprising a body and a float rod, said float rod slidably engaging said body, said cam body configured to actuate a motor actuation switch;
- and
- a sump pump actuation switch mounted within said cam actuator body, said cam actuator connected to said sump actuation switch and to the motor actuation switch.
A method of assembling a switch assembly for a sump pump for use in controlling a drainage level in a sump, the sump pump including a motor, a motor shell, and an end shield mounted to the motor shell, the switch assembly including a housing, said method comprising the steps of:
- connecting a cam actuator to the housing, the cam actuator including a body and a float rod, wherein the cam body is configured to actuate a motor actuation switch substantially simultaneously with an actuation of the sump pump actuation switch by the cam body;
- mounting a sump pump actuation switch adjacent to the cam actuator body, such that the sump pump actuation switch and the motor actuation switch are actuated by the cam body;
- and
- mounting a motor actuation switch adjacent to the cam actuator body such that the motor actuation switch is actuated.
A sump pump comprising:
- a motor comprising an end shield and a motor casing, said end shield mounted to said motor casing;
- a switch assembly for controlling energization of said motor, said switch assembly comprising a cam actuator comprising a body and a float rod, and a sump pump actuation switch mounted within said cam actuator body, said cam actuator connected to said sump pump actuation and a motor actuation switch, said float rod mounted adjacent to said sump actuation switch and said motor actuation switch.
