Abstract: A method for selectively restricting movement of an appliance position switch from a closed position to an open position includes positioning the pin within a channel of a body portion of a switch retention device and moving the body of the switch retention device in a first direction into an opening in a face of the appliance within which the pin is moveable from the open position to the closed position. Such movement is carried out to cause movement of the pin in the first direction toward the closed position. The method further includes continuing to move the switch retention device in the first direction such that a cap thereof contacts the face, and a tab extending outwardly from the body engages with the opening to retain the switch retention device in the opening and the pin in the closed position.

Abstract: A position switch retention device for use with an appliance including a body defining a first end, a cap extending outwardly from a second end of the body opposite the first end, and a first tab extending from a side of the body. The first tab defines a ramp extending away from the body to an edge directed toward and spaced from the cap.

Abstract: A position switch retention device for use with an appliance including a body defining a switch-receiving cavity open on at least a first end of the body, a cap extending outwardly from a second end of the body opposite the first end, and a first tab extending from a side of the body. The first tab defines a ramp extending away from the body to an edge directed toward and spaced from the cap.

Abstract: An appliance includes a position switch retention device for use with an appliance including a body defining a generally cylindrical profile extending through a first portion thereof along an axis and having a first radius. The body further defines a pin-receiving channel open on at least a first end thereof and positioned within the generally cylindrical profile. The device further includes a first tab extending from a side of the body. The tab defines a ramp and an edge with the ramp extending away from the first end of the body to the edge. A cap extends outwardly from a second end of the body opposite the first end. The cap is spaced apart from the edge of the tab at a first distance and has a second radius greater than the first radius.

Abstract: An appliance is protected against ground faults by a ground fault interrupter (GFI) that sends a signal to an AND gate between the GFI and a controlling microprocessor on one side and a load relay for operating a load device in the appliance on the other side. The GFI signals a ground fault directly to the load relay causing it to deactivate the load device. The appliance is also protected against reverse polarity by a flow detector circuit that signals the load relay to deactivate the load device in a reverse polarity condition.
