Toggles Series YB2 Rockers Distinctive Characteristics Pushbuttons 24mm square and 25mm diameter pushbuttons 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 18mm square and 19mm diameter actuators. D Short body of .965” (24.5mm) conserves behind-panel space.

Toggles Series YB2 BRIGHT & SUPER BRIGHT LEDS Rockers 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.

Toggles Series YB2 BALLAST RESISTOR CALCULATION FOR LEDS R Rockers If the source voltage is greater than the rated voltage of a lamp or LED, a ballast resistor must be connected in series with the lamp. This circuit diagram and formula will assist in calculating the value of the required ballast resistor.
