EButton sizes The provision of four types of button sizes (6 square type, 8 square type, 10 square type and 12 square type), it is possible to a sense of unity in panel designs. EDepth behind panel The overall length of switches is unified at 18mm. A short depth behind the panel of over 12mm. EIllumination component LEDs are used as the light-emitting devices to achieve full-face and dual color. The soft illumination produces a high-quality feeling. ESwitch component The use of a twin contact structure ensure high contact reliability. Can be used from a minimum load of DC 1.5V, 10ìA. Two types are available, with and without a click-feel. ETerminal This is a product designed to prevent flux entry when mounting. EAccessories Cosmetic flanges are available for the 10 square type and 12 square type buttons, broadening the scope for designs. EDesign A soft design with attention to fine details such as the rounded finish given to corners. Responsive tactile feedback offering two types, with and without a click-feel. The rich lineup of options broadens the scope for designs. KC Gold-Plated More than 100Mð— at 500V DC
