The S306 Series, which is manufactured by Schaltbau, is a cam-operated switching element suitable to use for AC, and DC voltages. Models without permanent magnetic blowout are specifically designed for AC voltages.
The S-shaped layout of the fixed contacts together with the contact bridge forms an adequate blowout area where the arc is thrust outside even with alternate currents. It has a compact design, and it has a mechanical endurance of up to 5 million operating cycles.
