The electronic schematic symbol for a simple single-pole, single-throw (SPST) relay is shown here: A coil of wire wrapped around a laminated ferrous core provides the magnetic field necessary to actuate the switch mechanism, energized byeither AC or DC voltage, depending on the model. This el...
Electromechanical relays may be connected together to perform logic and control functions, acting as logic elements much like digital gates (AND, OR, etc.). A very common form of schematic diagram showing the interconnection of relays to perform these functions is called a ladder diagram. In a ...

In the even t of a fault, welded contacts are forced open by the motion of the safety guard or E-stop device. This symbol denotes mechanically linked contacts; if one contact welds closed, all other dependent (auxiliary) contacts remain in position (that is, they cannot change state). 4...
