Ultra-Thin Pushbuttons Series GB2 Distinctive Characteristics Unique, off-center actuator allows high density setup and easy actuation while avoiding accidental operation in compact environments. Side-by-side, block mounting can be achieved by use of bracket AT546 on straight PC mounting types. Off-Momentary On Circuit. Black, white, and red snap-on caps available. Extremely thin size allows high density PCB mounting and makes these switches ideal for handheld equipment. Award-winning STC contact mechanism with benefits unavailable in conventional mechanisms: smoother, positive detent actuation, increased contact stability and unparalleled logic-level reliability. (Additional STC details in Terms & Acronyms; see Supplement section.) Molded-in, epoxy sealed terminals lock out flux and other contaminants. .100” x .100” (2.54mm x 2.54mm) terminal spacing conforms to standard PC board grid spacing for straight and angle mounting.

See Profile B in Supplement section. Manual Soldering: 4 seconds maximum @ 390°C maximum. These devices are not process sealed. Hand clean locally using alcohol based solution. See Cleaning Specifications in Supplement section. UL94V-0 actuator, case, & base The GB2 Series pushbuttons have not been tested for UL recognition or CSA certification. These switches are designed for use in a low-voltage, low-current, logic-level circuit. When used as intended in a logic-level circuit, the results do not produce hazardous energy.
