Study Notes
Electrical and Electronics Symbols
-
Wires and Connections
- Electric wire symbol represents a single conductor.
- Connected wire symbol indicates wires that are connected when crossing.
- Not connected wire symbol shows wires that are not connected at a crossing.
- Difference between a wire (single conductor) and a cable (multiple conductors bundled).
Relay Symbols
-
SPST Relay
- Symbol signifies a relay that closes connections using an electromagnet.
-
SPDT Relay
- Represents a relay that opens connections via electromagnetic control.
-
Function of Relays
- Relays act as electrically operated switches that open and close circuits, receiving signals from external sources.
Earthing Symbols
-
Earth Ground
- Symbol denotes zero potential reference for electrical shock protection.
-
Chassis Ground
- Indicates a wire connected to the chassis of the circuit.
-
Digital Ground
- Refers to the voltage reference for digital signals in an analog framework.
Switch Symbols
-
SPST Toggle Switch
- Symbol indicates a switch that disconnects current when open.
-
SPDT Toggle Switch
- Represents a switch that selects between two connections.
-
Push Button Switch (N.O.)
- Denotes a momentary, normally open switch used for temporary connections.
-
Push Button Switch (N.C.)
- Represents a momentary, normally closed switch that interrupts current when pressed.
-
DIP Switch
