This alligator clips insulting the crocodiles! If you want to open the snout, shifts the Isolierbezug, it makes Rapp and the muzzle is adjacent to the substrate, which they wanted to reconnect, closed. The Isoliermatierial is too soft, too slippery to wobbly. I advise against purchasing these parts, because one in which Gefingere at the terminals but then may slip again point the finger at the metal and it burns one if one has the thingy applied to the corresponding voltage.
