22mm Panel Seal Pushbuttons
Series YB2
Toggles
Distinctive
Characteristics
22mm pushbutton with the shortest above-panel dimension (1.8mm) in the industry
for splashproof design.
Meets IP65 of IEC60529 standards (similar to NEMA 4 and 13), providing
dust tight and splashproof panel seal protection.
Tamper resistant 19mm diameter actuator.
Short body of .965” (24.5mm) conserves behind-panel
space.
Distinctive long stroke and light touch actuation for clear
indication of circuit status.
Choice of cap colors includes clear, red, green, amber,
or metallic silver for enhanced panel appearance.
Metallic silver cap option has bright ring illumination.
Brilliant illumination with multiple LED colors.
Bezel color options in silver or black.
Available in momentary and alternate action with latchdown.
Crisp actuation and clear circuit status provided by snap-action
contact mechanism. Arc barrier protects against crossover.
Combination solder lug and .110” quick connect terminals. Terminals
are epoxy sealed to lock out flux, dust, solvents, and other contaminants,
as well as to secure terminals and improve contact stability.
Custom legends on actuator available.

The electrical specifications shown are determined at a basic temperature of 25°C. LED circuit is isolated and
requires an external power source. If the source voltage exceeds the rated voltage, a ballast resistor is required.
Base of AT634 and AT636 is Black for 5V, Light Blue for 12V and Gray for 24V.
