Peoples....One of my subscribers has asked: " Do these Horstmann [ Vmk ] timeswitches self-wind, to maintain their spring reserve, and also to self-rewind should the spring reserve have become exhausted after a prolonged power-cut, given the fact that these timeswitches are usually in a tamper-resistant casing, thus inaccessible to the electricity consumer without causing a criminal offence of opening the case to manually rewind the spring reserve?" VERY GOOD QUESTION !! This will be investigated. For as long as I have owned Horstmann Vmk timeswitches, one thing that I have never done, because it's never crossed my mind to give it a go, is to energise one of these Vmk timeswitches with an unwound spring reserve, in order to find out whether it will self-rewind, and whether a couple of weeks later, I will find the time switch in an energised, fully-wound state. So then! Over the next few weeks, I will take a Horstmann V Amk 9 SRS, as I already have one of these wired, ready-to-go, and just energise it on the mains with an unwound spring reserve, to see what the outcome is, and to confirm whether-or-not these time switches self-rewind. THIS COULD BE INTERESTING ! For those of you who would be interested in a more in-detail video of either the Horstmann Vmk 7 SRS, or the mentioned V Amk 9 SRS, please look in my videos list, as I do have more in-detail videos on BOTH of the timeswitches, and those videos ARE ALREADY LOADED for you to enjoy! YAY! Please return in mid January 2012 to see what the outcome of this experiment was! The timeswitch either will, or will not self-rewind. Place your bets now! :-D -BoomBoxDeluxe. __________________________________________ Tags used in this video: Timeswitch, Time switch, Timeclock, Time clock, Timer, RateChanger, Rate changer, Tariff Changer, Economy Seven, Economy 7, Off Peak, Dual Tariff, Off-Peak, Horstmann, V mk Range, Vmk Range, VA mk Range, V Amk Range, V mk7 SRS, V mk 7 SRS, Vmk7srs, BoomBoxDeluxe ----------------------------------------------------------------------------------- end.
