Scottsdale, Ariz. NKK Switches offers a new series of miniature snap-acting pushbutton switches that offer hundreds of combinations. The MB2400 series momentary action pushbuttons feature a snap-acting mechanism that provides a smooth actuation, a short stroke, light touch and audible feedback.
These new switches are available in single-pole or double-pole models, with gold, silver, or gold over silver contacts. The series is rated at 3A at 125 V ac for silver, 0.4 VA maximum at 28V ac/dc for gold, or a dual rating when gold over silver is specified.
The design selection includes devices with bushings as well as snap-in mounted versions. Bushing mount models feature a high torque bushing construction that prevents rotation or separation from the frame during installation. Engineers can specify a multitude of bushing options such as different heights, smooth or threaded with keyway, round or D-flatted shapes.
Terminal options include solder lug, straight PC (with or without bracketing), wire wrap, as well as vertical and right angle PC mounting. The straight PC versions come in many different terminal lengths with standard or reinforced brackets. The plungers are metal, ensuring durability, and are designed to accept different sized snap-on caps, which are available in a variety of colors.
Snap-in mount versions are available in a variety of configurations. There are four different bezel styles, three of which allow LEDs to be mounted within the frame of the bezel. Engineers can choose a single LED in green or red, or dual LEDs in red, green or yellow. In addition, for dual LED versions, either round or rectangular LEDs can be specified. The MB2400 series can be used to indicate status at a single glance.
In addition, the MB2400 series features an anti-jamming design to protect the contacts from excessive downward force on the actuator, and stainless steel frames to resist corrosion. Terminals are epoxy-sealed to prevent the entry of solder flux and other contaminants. All devices feature a long mechanical life of 200,000 operations minimum. This series is UL Recognized and CSA Certified. UL94V-0 versions are available.
NKK offers these devices completely pre-assembled at no additional charge. Panel cut-out sizes vary based on configuration, ranging from 13.1 x 15 mm to 18.4 x 15 mm. Available terminations include solder lug, straight PC and wire-wrap. The 11.5-mm square pushbutton cap lends itself easily to legending. Legend packets are available online or upon request.
