Certainly, wiring marine rocker switches involves understanding the specific type of switch you’re dealing with, as each has its own configuration and purpose. Below is a simplified guide on how to approach terminal block wiring for some common types of marine rocker switches based on the descriptions provided.
SPST Rocker Switch (V1D1-B60B)
- Type: Single Pole Single Throw (SPST), ON-OFF
- Terminals: 3
- Wiring Overview:
- The middle terminal is for the power source (12Vdc).
- One of the outer terminals connects to the load (device you want to control).
- The remaining terminal is for the ground connection for the lamp inside the switch.
SPST with Independent Lamp (V1D1-G66B)
- Type: SPST, ON-OFF with independent lamp
- Terminals: 4
- Wiring Overview:
- Similar to V1D1-B60B for power and load connections.
- The additional terminal (terminal 8) controls the independent lamp. Connect it to a power source that is separate from the switch operation.
DPDT Rocker Switch (VJD1-D66B)
- Type: Double Pole Double Throw (DPDT), ON-OFF-ON
- Terminals: 7
- Wiring Overview:
- Two middle terminals connect to the power source.
- The outer pairs of terminals connect to your two loads.
- The bottom light is wired to light up in one position, and the top light in the other position.
DPDT with Independent Lamps (VJD2-U__B)
- Type: DPDT, ON-OFF-ON
- Terminals: 10
- Wiring Overview:
- Middle terminals for power sources.
- Outer terminals for two different loads.
- Four terminals make the lights function, controlled by external sources.
DPDT Momentary (VLD1-A_0B)
- Type: DPDT, (ON)-OFF-(ON) momentary
- Terminals: 8
- Wiring Overview:
- Middle terminals for power.
- Outer terminals for reversible motor control or similar applications.
- Independent lamp can be wired to illuminate separately from the switch operation.
DPDT Momentary with Mixed Lamps (VMDJ-G66B)
- Type: DPDT, (ON)-ON-OFF
- Terminals: 6
- Wiring Overview:
- Middle position is ON, connecting two terminals for power.
- Top momentary ON connects an additional terminal for starting applications.
- Includes a brass jumper for special applications like windshield wiper/washer setups.
Specialty Wiring
For specific applications like Nav/Anchor lighting or bilge pump controls, refer to specialized wiring diagrams that match your exact switch model. These typically involve more complex connections to accommodate the functionalities like automatic operation or dual-function switches.
Remember, safety first. Always ensure your switch ratings match or exceed your application requirements, and if unsure, consult a professional electrician or marine technician.
