Abstract
An apparatus for selectively activating a food waste disposer for a sink may include a housing and an activation member. The housing may include a switch and a first magnet. The first magnet may be movable relative to the housing and the switch between first and second positions. Movement of the first magnet from the second position to the first position may cause corresponding movement of the switch from an off-position in which electrical current is prevented from reaching a motor of the disposer to an on-position allowing electrical current to the motor. The activation member may include a second magnet and is receivable in a tubular member through which waste drains and positionable relative to the tubular member to place the second magnet in proximity to the first magnet to generate a repulsive magnetic force that moves the first magnet between the first and second positions.
