See Profile A in Supplement section. Manual Soldering: See Profile B in Supplement section. These devices are not process sealed. Hand clean locally using alcohol based solution. The DB Series pushbuttons have not been tested for UL recognition or CSA certification. These switches are designed for use in low-voltage, low-current, logic-level circuit. When used as intended in a logic-level circuit, the results do not produce hazardous energy. Supplement Accessories Light Touch Miniature Pushbuttons C18 www.nkk.com Toggles Series DB Rockers Distinctive Characteristics Both PCB and panel mounting options available. C Programmable Illuminated PB Choice of cap sizes in .315” (8.0mm) and .394” (10.0mm) diameter cap design for simple, snap-on installation. Pushbuttons Light Touch Miniature Pushbuttons High torque bushing prevents rotation and separation from metal frame during installation. Keylocks Stainless steel frame resists corrosion. Rotaries Snap action contacts give smooth actuation, short stroke, light touch, and audible feedback. This mechanism also provides long mechanical life. Slides Molded-in terminals prevent entry of solder flux, dust, and other contaminants. Touch Tilt Tactiles .100” x .100” (2.54mm x 2.54mm) terminal spacing conforms to standard PC board grid spacing. Round terminals for easier through-hole mounting on PC boards.
