The SF337C Emergency Shower Switch is for any location where activation of an emergency signal is required. The design is such that it may be located anywhere in a shower, bath or tub room, regardless of environmental conditions. The combination of rubber-grommetted mounting screws, rubber mounting gasket, and completely sealed front faceplate make it waterproof (if properly installed). Electronic components are mounted on a circuit board, including an industry-proven reliable reed switch for circuit initiation. The activating magnet is mounted on the large pull-down lever, which is completely sealed in plastic. The indicator LED is also completely sealed.

Due to the flexibility of its design, the SF337C may be used as a pull cord or as a pull down activated emergency switch. The pull cord supplied may be used for emergency call activation, or if desired, the large 1.1″ (28 mm) red pull-down lever may be used. Dome light and system annunciation vary according to the manner in which the SF337C is connected.
