Standard electrical iec symbols also known as iec 60617 british standard bs 3939 used to represent various devices including pilot lights relays timers and switches for usage in electrical schematic diagrams.

Relay symbol electrical drawing. Electrical symbols switches and relays. Contacts time delay after coil normally open normally closed normally open normally closed relay etc. Electrical symbols are used to represent. An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions such as wires batteries resistors and transistors in a schematic diagram of an electrical or electronic circuit these symbols are largely standardized internationally today but may vary from country to country or engineering discipline based on traditional conventions.

Most of the time a small voltage or current is used to switch other voltages or higher currents that may be electromechanical or fully electronic type.
