1 TEST SWITH STT type TEST SWITH High safety and contact reliability lever operation type Test Switch onformity with major standards STT type conforms to IE0- and applies to UL. Open-ircuit prevention Internal circuit of and S units (for urrent ircuit) is double, which certainly prevents Open-ircuit during inserting a plug. Plug Internal ircuit Wire dropping-off prevention The rib on the terminal portion leads a ring tongue to proper position. This structure prevents improper connection of the screw and ring tongue. Easy voltage test by general clips oltage circuit testing can be easily conducted by general clips like an alligator clip as well as dedicated plugs. Efficient wiring work by Up-Screw Terminal Up-Screw terminal makes wiring work more efficiently. High contact reliability by -point contact The multi point contact structure of clips enhances contact reliability. -point contact

2 STT type TEST SWITH Safety Structure STT type is high safety structure. Wire holes Separators W i re s c a n b e a t t a c h e d t o prevent cover removal. Protective separators are set up between units to prevent easy finger touch on live portion while levers are disconnected. lip portion Terminals lips are in deep-set position from surface, and fingers do not reach to live portion. Screw terminals are finger protective structure.
