Habistat Sun Switch, Day On.
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.
