NKK Switches Featured Products

NKK Switches M Series Toggle Switch Kit

NKK Switches M Series Kit contains the M Series Toggles that feature a standard anti-rotation design on non-cylindrical levers that mates the toggle and bushing. There are two flatted sides on the bottom of the toggle which fit into a complementary opening inside the bushing. There is also an anti-jamming design to protect contacts from downward force, high torque bushing construction, and high insulating barriers to increase isolation of circuits in multipole devices, which also provides added protection to the contact points. The NKK Switches M Series Toggles have a molded diallylphthalate case (UL flammability rate of 94V-0) and epoxy sealed terminals to prevent entry of solder flux and other contaminants. The M Series Kit contains bushing mount, bracket PC mount, and angle PC mount styles.

NKK SK Series Antistatic Keylock Switch

NKK SK Series Antistatic Keylock Switch features snap-in mounting and short below-panel dimensions. This switch can withstand 15 KV of ESD. The below-panel length of 22.7mm provides greater design flexibility. Other features include 45º angle of throw and operating temperature of -40 to 185ºF.

NKK Switches YB2 Series 24mm Panel Seal Pushbuttons

NKK Switches YB2 Series 24mm Square and 25mm Diameter Panel Seal Pushbuttons are thin flush mount push button switches. The series offers the shortest above-panel dimension (1.8mm) in the industry for IP65 splash-proof design. Behind-panel space is conserved with a .965" (24.5mm) body. Six LED colors are available as well as five cap colors, including a metallic silver button for non-illuminated versions. NKK Switches YB2 Series 24mm Panel Seal Pushbuttons have a flammability rating of UL94V0 and are cULus Recognized. Mechanical life is 1,000,000 operations minimum for momentary circuits, and 200,000 operations minimum for maintained circuits. Electrical life is 100,000 operations minimum.

New! Square Actuator pushbuttons for the YB2 series are now available! View square versions.

NKK Switches FR02 Series 10mm SMT DIP Rotary

NKK Switches' FR02 Series 10mm SMT DIP Rotary has the lowest profile in the industry and allows close stacking of PC boards. With a slim body of .150"(3.8mm), NKK Switches' FR02 Series has highly visible legends and a choice of either screwdriver or a new shaft actuator option. In addition, this low-profile switch offers a detent mechanism that gives crisp, positive action for accurate switch setting. Other features and benefits include heat-resistant resin that allows infrared convection reflow soldering, gull-winged terminals for mechanical stability during soldering and simplified solder joint inspection, cam-activated movable contact and gold contacts for contact reliability and continuity, tape-reel packaging that meets EIA-481-2 standard, and coplanarity (all considered surfaces must lie between two parallel planes that are a maximum distance apart of .0059"(0.15mm)).

NKK JWLW Series Molded Rocker Switches

NKK's JWLW Series comprises the industry's first molded Rocker Switch with TV rating. These switches have sealed panels and are designed to handle large inrush current, with high electrical capacity of 16 Amps at 125/250 V AC. JWLW switch models are certified for TV-8 rating and meet IP67 of IEC60529 standards. Other features of NKK's JWLW Series molded Rocker Switches are exterior seal of acrylonitrile butadiene rubber covering a flat flange, black or red switch caps, black housing, solder lug/quick connect terminals at .187"(4.75mm), double pole single throw (DPST) and double pole double throw (DPDT) switch dimensions, unique construction to break light contact welds, increased electrical life with specially designed plate to minimize contact bounce, interior cover for dust resistance, molded terminals and sealed epoxy to lock out dust and other contaminants, and housing and case made of heat-resistant resin that meet the UL94V-0 standard. JWLW Series Rocker Switches were designed for use as "Power On" devices in equipment where a high tungsten inrush current is anticipated.

NKK FT Series Resistive Touch Screens

NKK FT Series 5-wire, 4-wire, and digital resistive touch screens are engineered to complement the application of choice while offering superior durability and flexibility. NKK FT transparent touch screens include options in multiple sizes and choices of input by finger, gloved finger, or stylus. Whether an application requires the 5-wire or 4-wire technology, the features include metal tails (analog), contact reliability with a connector, and ANR film, eliminating many of the typical visual artifacts. The film surface is non-glare and hard coated for ease of use and integrity of the surface. NKK 5-wire touch screens are highly resistant to static electricity and noise pollution and offer drift-free operation despite any temperature fluctuation. These FT Series devices are ideal for use in a variety of applications, including information kiosks, industrial automation, medical equipment, banking / exchange management systems, and more.

NKK Switches KP Series RGB LED Illuminated Pushbuttons

NKK Switches KP Series RGB LED Illuminated Pushbuttons are available with built-in RGB LED illumination, which allows for the creation of unlimited color combinations, as well as super bright red and green built-in LEDs. The KP Series features a unique actuation guide that gives a positive indication of circuit transfer as well as smooth and silent operation (choices of tactile, nontactile or tactile/audible actuation). Cap selection includes sculptured, flat, and home key. With a compact design height of .906" from PC board to top of cap, the NKK Switches KP Series RGB LED Illuminated Pushbuttons feature a specially designed snap-in standoff for simple and secure PC board mounting and alignment. Electrical capacity (resistive load) is 100mA max @ 12VDC.

NKK Switches MB2400 Series Snap Action Pushbutton Switches

The NKK Switches MB2400 Series Snap Action Pushbutton Switches offer a short stroke with a light touch giving a smooth actuation and audible feedback for a 200,000 operation minimum rating. The miniature snap-acting, snap-in mount pushbuttons are available in a comprehensive array of bezel styles, colors, and LEDs to enhance the appeal and functionality. An anti-jamming design protects the contacts from damage due to excessive downward force on the actuator. Installation is simplified by the longer center solder lug terminal and the high torque bushing construction to prevent rotation or separation from the frame. The NKK Switches MB2400 Series Snap Action Pushbutton Switches are constructed of a stainless steel frame to resist corrosion, an internal o-ring to protect against contamination, patented silver contacts of specially composed alloy for hardness, and epoxy sealed terminals to prevent entry of solder flux and other contaminants.

NKK Switches OLED Smartswitch™ Rocker

NKK Switches offers the Smartswitch™ programmable display Rocker (patent pending) featuring sharp contrast and high resolution (96x64 pixels) organic LED technology (OLED) with 52,000 hours at 30% illumination. The Smartswitch Rocker can replace multiple switches and displays with one small package device through its multifunction actuation navigation - forward, reverse, up, and down, with push for activation. The NKK Switches Smartswitch Rocker is panel mount with easy, snap-in installation and a connector socket is available for simple connection (AT715).
