ALCOSWITCH Blue Series Pushbutton Switches
Description
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.
