Wires, Feeders, Switches, Connectors Circuit Symbols

- circuit symbols or circuit diagram symbols for electronic components: wires, feeders, switches & connectors.

There are many different circuit symbols for wires, feeders,connectors and switches, etc.

This page provides electronic component circuit symbols for wires, feeders, connectors and switches.

These electronic component circuit symbols are based on those that appear to be most widely used.

Wire circuit symbols

The selection of schematic symbols for wire:




Crossed wires


Crossed wires (alternative which is less standard these days).


Joined wires


Joined wires


Coax feeder


Shielding / screening


Test point or terminal

Switch circuit symbols

The selection of circuit diagram symbols for switches:




Switch (SPST)


Switch (SPST - normally closed)


Switch (SPST - push button / momentary action)


Switch (DPST)


Switch (SPDT)


Switch (Single pole four way)

Note abbreviations for switches include:
    SPST: Single pole single throw
    DPST: Double pole, single throw
    SPDT: Single pole, double throw
    DPDT: Double pole, double throw

The number of "throws" equates to the number of active positions on the switch, and the number of poles equates to the number of circuits that are switched.
