Sangamo Round Pattern Time Switch - Q551/13


Solar Dial quartz controlled with battery reserve, 3 pin base. Form 13 version, gives one ON and one OFF operation per day. The ON operation always tracks SUNSET while the OFF operation can be made either to track SUNRISE, or to occur at a fixed time between 8:30pm and 1:00am. The Solar Time Switches are ideal for applications which require control linked to sunset and sunrise times. Popular applications for solar time switches include street, stairwell and security lighting. Cost Savings: Once set, the switches track SUNSET and SUNRISE throughout the year, without the need to sense light levels. This avoids the installation and maintenance problems associated with photo sensing devices and means they can be left to operate unattended for years.
