The Franke Little Butler Food Waste Air Switches increase safety around the sink. Conventional electrical switches in proximity of a kitchen sink place the user at risk from electrocution, not so with an air-powered switch. Combined with the FK-WD9088 Controller, these switches power a Franke food waste disposer via an air current, keeping the user out of harmís way. The function of the switch is not affected by water, so the switch can be mounted right next to a faucet for convenient access. Choose from Chrome, Polished Nickel, Windsor Bronze and Satin Nickel finishes.
