NKK Switches announces the availability of the MB2400 Series of miniature, snap-acting, snap-in mount pushbuttons. The series provides a comprehensive array of options designed to suit any application requiring a unique combination of innovative design and aesthetic appeal at an affordable cost. With four different bezel styles and seven standard bezel colors to choose from, design engineers can be creative in their configuration of MB2400 Series momentary-action devices. The bezel colors serve as frames to enhance both the appeal and functionality of the devices.There are three bezel options that feature built-in LEDs. Choices range from one round LED to two round LEDs to two rectangular LEDs. The LEDs enable MB2400 Series switches to be used to indicate status at a glance.As another way to provide engineers with the opportunity to customize their MB2400 Series devices, the 11.5mm square pushbutton caps are available in seven colors and adding legends is a simple process, with NKK featuring a wide range of legend options.  The series, which also features a short stroke, light touch and audible feedback, provides engineers with not only a wide range of options, but also high reliability. Mechanical life for the MB2400 Series is rated at 200,000 operations minimum.The anti-jamming design of these miniature pushbuttons, protect the contacts from damage due to any excessive downward force on the actuator.  Also, prominent insulating barriers increase insulation resistance and dielectric strength. In addition, the stainless steel construction resists corrosion and the epoxy sealed terminals prevent the entry of flux and other contaminants.Available in single pole or double pole, ON (ON) momentary circuits, engineers can specify gold, silver or gold over silver contacts. These devices are rated at 3A @ 125V AC with silver contacts, 0.4VA maximum @ 28V AC/DC with gold contacts or both ratings when gold over silver contacts are specified. Terminal options include solder lug or straight PC.NKK offers these push-button switches completely pre-assembled at no additional charge. Panel cut-out sizes range from 13.1mm x 15mm to 18.4mm x 15mm. The MB2400 is rated UL94-V0 for flammability, and meets UL and CSA standards.
