Wires, Feeders, Switches, Connectors Circuit Symbols
- circuit symbols or circuit diagram symbols for electronic components: wires, feeders, switches & connectors.
Electronic component circuit symbols includes:
• Circuit symbols overview
• Passive component symbols
• Semiconductor diode symbols
• Transistor / FET symbols
• Wires, switches, connectors
• Logic symbols
• Analogue circuit blocks
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 wire electronic circuit diagram symbols:
![]() |
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.
