ALCOSWITCH Blue Series pushbutton switches for power and signal applications incorporate an innovative snap-action mechanism that produces an extremely fast switching moment. This high level of dynamics not only reduces arcing and bounces but also provides a high number of electric lifecycles. In addition, the push-on/push-off version of the switches produces a clear tactile, audible feedback to indicate that they have been properly pressed.
ALCOSWITCH Blue Series pushbutton switches are available in single-pole, double-pole, and double-throw configurations (SPDT, DPDT) with push-on/push-off or momentary function. Their brass internal contacts have a silver inlay, and optional gold plating is available for signal transmission up to 60mA at 30V DC. The silver inlay contacts have an initial resistance of ?10 milliohms at 125V AC, at 1 A at 2 to 4V DC. For gold-plated contacts, the resistance is ?20 milliohms at 100mA at 2 to 4V DC. Equipped with silver inlay brass contacts, the pushbutton switches are rated up to 250V AC at 1.5 Amps for European applications and up to 125V AC at 3 Amps for North American applications.
The silver-inlay version’s electric lifecycle is 25,000 cycles at full current and voltage rating (resistive), and the gold-plated version is 50,000 cycles at full current and voltage rating (resistive). This compares to the UL requirement of 6,000 cycles at load.
