VJD1-D66B ON-OFF-ON Rocker Switch

The VJD1-D66B is a very common and very flexible rocker switch.  It is Double Pole Double Throw (DPDT) and it’s function is ON-OFF-ON.  It has two dependent lamps, one at the top and one at the bottom  (What’s this?).  This switch would be used when you want to feed (2) loads from 1 or 2 sources (like a boat’s navigation and anchor, or a car’s turn signal).  The lamps act as indicators when the switch is on.

This switch may also be used as a SPDT switch by simply not using 3 of the terminals.

We say it’s flexible for a reason: Notice in the wiring schematic, that the two halfs of the switch are isolated from each other… and the lamps are only wired into one side of the switch which allows flexibility to use the right side (pins 4-5-6) for switching, and the left side (1-2-3) for illumination of the lamps.  With pins 1-2-3 and 4-5-6 isolated, you can provide two different inputs… for instance, you could put 12V+ into pin 2, and 12V- into pin 5, and with a few jumpers can reverse polarity on an electric motor!

This is a rocker switch body only.  This V-series switch is meant to be paired with our custom etched rocker actuators (covers) or other actuators for a complete switch unit.  All actuators sold on this site will fit this switch.  When using our custom etched actuators you probably would want to add a “Bottom Lens” for this switch (What’s this?).

Like all our rocker switches this is a genuine Carling Technologies product.  It is IP68 sealed dustproof and waterproof.
