Switches are of a diverse variety, for example, single-pole single-throw, pushbutton, dip, relay, and more. A switch connects a circuit when it is closed and disconnects the circuit when open. Resistor Resistors in an electrical diagram look like wavy lines with pointed ends. The resisto...
Disconnects the current when open. We're showing a simple SPST (single-pole single-throw) toggle switch, but there are variations for SPDT, pushbutton, dip, relay, and more. For a complete list of switch symbols, check out SmartDraw's electrical symbol library. ...

Not all standards, such as the IEC standard, have a symbol for this device. Fused Disconnect Switch Main disconnect switches on electrical panels are represented with a vertical switch symbol—if fused, the fuse symbol is added to the bottom. These symbols can typically be found on the high...
Overload relays — disconnect the load automatically when an overload or excessive current is detected. Latching relays — keep up their position after being activated. Safety relays — are used to ensure safety and reliability in critical systems. ...
Electric Bell This is the symbol of Bell which Rings when activated. Fuse The fuse disconnects when the current is above the threshold---used to protect a circuit from high currents. Bus The bus symbol contains several wires. Usually for data/address. Loudspeaker Convert electrical signals to ...
