Because [this] https://de.wikipedia.org/wiki/Spannungspr%C3%BCfer#/media/Datei:Kenden_Driver2.JPG https://de.wikipedia.org/wiki/Spannungspr%C3%BCfer#/media/Da... is all that is needed to do it. Can you think of a way to do this safely with less commonly available electronics? Get rich quick! :-)
- OJFord 5y agoSure, but you could also say 'all that's needed' is an appropriately rated multimeter, no need for a 'Spannungsprüfer' (I don't speak German btw!). Those neon/LED drivers (non-(intended)-contact) are in basically every 'dad toolbox' and 'man drawer', a VDE 1000v rated one just seems appealing/like it'd sell well, even if sure, people who actually need that (or should be doing things that do) have better tools for it.
- LargoLasskhyfv 5y agoI posted that link because I didn't find any other one which illustrated the point I tried to make so well with one large picture. To put it in different words: this exists like pictured because it is the most simple and cheap method to safely implement with currently available parts.
