The maintain toggle switch (SP/DT) is the standard switch which is sent with shades. Maintain switches when flipped stay in the up or down position for one to walk away while the shade moves. Ivory is the standard color, but white is also available. This switch is rated for 110-230V and 15A. This means that US and export markets can use the switch and the motor draw through the switch can be up to 12A. The switch fits in a single gang box and uses a conventional light switch cover plate.
