for certain purposes the best device

I have some electronic switching devices that are equipped with all the trimmings, but unfortunately, with back-up batteries. When not using the batteries would therefore have to remove (2 screws, cover, and Mini button batteries in bag, cover it and screw back into it), or the things must always be left in sockets.
Since I only need the function of several daily switching times, and this is not the minute, I decided to be operated timer for this manually. Those things are just great. Robust simpelst to adjust (without having to use fingernails or pen tips), also be used for double sockets. Those like me who can do without all the electronic Klim-BIM, with this switch, the one at that makes a very robust, well served.

Summary:
- Simplest adjustable, precisely if only to 15 minutes
- Compact design
- Robust
- Switch for automatic and continuous operation
- Not cheap, but absolutely worth the price
