- Electronic, light activated switch for mains equipment
- Switches up to 600 watts off when the light levels fall and on again when they brighten.
- Used in sophisticated management of environmental heating and lighting
The Sun Switch is a light activated mains electricity switch. When the Sun Switch is in the light, the power will be switched on and when it is in the dark, the power will be switched off. The difference between the on and off levels has been adjusted so that the unit does not flicker at the triggering point nor will it switch on and off due to minor variations in brightness. Essentially, the unit detects day and night and can therefore switch things on that are required during daylight hours.
The range of items that can be switched is only limited by a maximum load of 600 watts and the imagination. Most uses will include switching those things that act like an artificial sun, that is heaters and lights. One of the major advantages of the Sun Switch is that natural day/night cycle is duplicated, including the seasonal variations of long day length summers and short day length winters.
The Sun Switch is the ideal unit to switch heaters and lights in sequence with the natural photoperiod. Because in nature the sun supplies both heat and light, it may be sensible to provide both from the Sun Switch. A simple multi-socket could be used as long as the total load does not exceed a maximum of 600 watts. In conjunction with a Sun Switch, the equivalent switching on of dark activated equipment can be achieved with a Moon Switch.
