SWITCHES USED IN MARINE CONTROL PANELS
SINGLE POLE, SINGLE THROW (SPST)
This is the most common type of switch used. It is the basic ON / OFF switch. There are five versions shown below. Diagrams 1 and 12 show the standard switch in two layout versions. Diagram 3, 7, and 9 show an illuminated versions. These switches are used anywhere an on off function is required. For example: cockpit light, bilge blower, windshield wiper, electric toilet, or in a momentary version an electric horn.
SINGLE POLE, DOUBLE THROW (SPDT)
This is simple switch like the SPST switch, but is much less frequently used. It is a two position ON / OFF switch, in that it can be used to turn two things on and off. The key is that only one can be on at any one time. There are five versions shown below. Diagrams 2 and 13 show the standard switch in two layout versions. Diagram 4, 8 and 10 show an illuminated versions. These switches are used anywhere a two position on off function is required. I.E. switiching between two operating modes. For example: bilge pump (automatic and manual), fuel tanks (port and starboard), various gauges including fuel level, (port and starboard). These are also available in a center off position where neither circuit is activated.
DOUBLE POLE, DOUBLE THROW (DPDT)
This is a common type of switch and is typically the most complex type of generic dashboard switch. It has what is equivilant to four ON / OFF switchs. It can be used to turn two things on and off in diferent combinations or four things on and off in pairs. There are five versions shown below. Diagrams 5 and 14 show the standard switch in two layout versions. Diagram 6 and 16 show two potential hookups for the switch. Diagram 15 shows a different configuration of switch as well as an illuminated version. These switches are used anywhere a two position, multiple combination, on off functions are required. I.E. switiching between two operating modes. For example: running lights (anchor and navigation), electric winches (up and down), generating 24 volts from a 12 volt system, or where there is a desire to disconnect both the positive and negative connections to a device. These are also available in a center off position where neither circuit is activated.
