ETC2 GB215AB-BA Ultra-thin pushbutton Datasheet

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.

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.
