Abstract of the Disclosure A closure for a drain port in a receptacle such as a bathtub or sink. The closure includes a base member for attachment to the receptacle. It includes a fulcrum which engages one side of a bi-stable disc spring. A pair of actuators are situated on the opposite side of the spring, and contact it respectively radially inwardly and outwardly from the fulcrum. The spring can be moved by the actuators to assume a respective one of its two stable configurations. The spring, when in one configuration, permits a seal to bear against a peripheral surface around the drain port to close it. When in the other configuration, it causes the seal to move away from the peripheral surface and open the drain port.
