Introducing
ALCOSWITCH Blue Series Pushbutton
The new ALCOSWITCH Blue Series pushbutton is based on an innovative snap-action
mechanism that produces an extremely fast switching moment. This high level of
dynamics not only reduces arcing and bounce but it also results in a high number of
duty cycles. The new series comprises versions with SPDT and DPDT configurations
and can be ordered with push on / push off or momentary function. The actuator cap
of the push-button switch is available in many colors and sizes.
KEY FEATURES
? Miniaturized snap acting pushbutton
? Contacts with silver inlay (high power) or
gold inlay (low current, SPDT)
? SPDT and DPDT
? 50,000 cycles for gold plating
? 25,000 cycles for silver plating
? Tactile and audible feedback
? Wire lug or PC board terminals
? Contact rating up to:
1.5A @ 250VAC (EMEA)
3A @ 125VAC (North America)
? Hardware included
? Boot Seals available
? Multiple actuator buttons available in both
color and size
OPERATING EFFICIENCY
This miniature pushbutton is easily integrated into compact control/front panels.
Despite its small case dimensions, the actuator gives a clear reliable feedback that
confirms proper operation. At 265°C the solder heat resistance of the
ALCOSWITCH Blue Series pushbuttons is high enough for efficient, RoHS compliant
wave soldering technology.
