The wiring diagrams presented below are for several common switching applications that you may want to wire through your WeatherDeck™ Panel, or through any branch circuit distribution panel. The schematic representations for switch actions are presented in the table below.
| SPST - Single Pole Single Throw |  |
| SPDT - Single Pole Double Throw |  |
| DPST - Double Pole Single Throw |  |
| DPDT - Double Pole Double Throw |  |
Horn SPST - OFF/(ON)
Navigation Lights (Independent bulb) SPDT - ON/OFF/ON
Bilge Pump SPDT - ON/OFF/(ON)
Trim tabs (independent operation of each tab) SPDT - (ON)/OFF/(ON)
Navigation Lights and Anchor lights (Shared bulb) DPDT - ON/OFF/ON
