1. V1D1-B60B  – SPST, ON-OFF, 1 Dep Lamp – Top

Buy This Switch: V1D1-B60B ON-OFF Rocker Switch.

Arguably the most popular rocker switch, the V1D1-B60B is a SPST ON-OFF rocker switch designed for 12V 20A applications. It features the “V1D1” marking along with the Carling Technologies branding for authenticity.

This Carling rocker switch includes a single incandescent lamp at the top, which automatically illuminates when the switch is ON. It has three prongs (terminals) on the back, ensuring a simple and reliable connection.

For those needing a four-prong version with two lights, we also offer the V1D1-G66B, listed below. Additionally, this switch can replace a V1DA rocker switch, which has plastic barriers between the terminals.

Like all of our Carling Contura V-Series Rocker Switches, this model is IP68-rated, making it dustproof and waterproof. For proper installation, refer to the rocker switch wiring diagram provided.

See our V1D1 wiring overview video here:

This switch body can be paired with many of our printed marine labeled snap in rocker switch covers for a complete, labeled switch combo unit.

As our only 10-terminal rocker switch, this marine-grade DPDT rocker switch is an ON-OFF-ON switch, where both the up and down positions are ON, and the center position is OFF. It features two independent lights—one at the top and one at the bottom—which are triggered by an external source, such as another switch.

The VJD2 rocker switch has 10 terminals on the back and is a variation of our VJD1 ON-OFF-ON rocker switch body. It is most commonly used when controlling two loads separately, without activating the backlights in a bank of backlit rocker switches.

Refer to the rocker switch wiring diagram to see how the 10 terminals (spade connectors) function:

  • Four terminals control the independent rocker switch lights
  • Six terminals handle electromechanical switching
  • Two isolated negative inputs (T9 and T7) for each LED or lamp

This rocker switch body is designed to be paired with a rocker switch actuator, and all actuators sold on our site are fully compatible. However, for independent lighting functionality, we recommend using an etched switch cover specifically designed for this model.

Commonly used as a Navigation/Anchor light switch for boats, this Carling Contura V-Series Rocker Switch is IP68-rated, ensuring it is dustproof and waterproof. For detailed installation guidance, refer to the rocker switch wiring diagram provided.
