3 Pole & Neutral Bypass Changeover Switches
The By-pass changeover switches in it's different series, are
manufactured with high safety self-extinguishing materials,
providing an excellent level of electrical insulation, low smoke
emissions and high resistance to electromechanical stress.
They comply with environmental requirements and undergo strict
quality controls for a reliable product that meets the most
They consist of a sandwich type bosy containing self-cleaning blade
type contacts, with pre-arc zones to ensure long term, fault-free
eneergy transmission and coasted with silver alloy for long
electromechanical life. The detent mechanism provides quick and independent
switching due to the accumulation of elastic potential energy, which is
transmitted at high speed to the contacts for arc extinction.
