buna tuturor,as vrea sa copiez un declansator(cel din imagine), dar singura problema e ca nu cunosc componenta principala... e fototranzistor? fotorezzistenta? fotocelula?... nu scrie nimic pe ea.aceasta foto-ce-o-fi-ea declansaza tiristorul de sub ea, nu are nici o sursa de alimentare.multumesc.PS: oare o gasesc la vreun magazin de specialitate sau doar comandata?
