Snap-in Miniature Rockers
Series MLW
Toggles
B
Industry’s first miniature snap-in, lighted rocker switch.
Actuators in various styles operate with firm, well-defined
movements.
Interlocking actuator prevents switch failure due to
jamming or window locking.
Two bezel sizes adapt to varied panel cutouts.
Unique stainless steel retaining clips securely hold
switches over a range of panel thicknesses, even
when exposed to vibration.
Space conserving front panel mounting with
minimum behind panel dimension of .902”
(22.9mm).
Durable stainless steel housing prevents corrosion.
Isolated lamp circuit for incandescent, LED, and neon lamps.
Front panel relamping.
Built-in protective cover shields contacts from dust.
Epoxy sealed solder lug terminals lock out flux, dust, and other
contaminants.
Extended lamp terminal for ease of wiring.
Matching indicators available.

LAMP CODES & SPECIFICATIONS
Electrical specifications are determined at a basic temperature of 25°C. Lamp circuit is independent of switch operation.
For dimension drawings of lamps see Accessories & Hardware section.
For neon, if the source voltage is greater than rated voltage, a ballast resistor is required.
The ballast resistor calculation and more lamp detail are shown in the Supplement.
