ELECTRICAL ACTUATION METHOD




























                    Figure 11.3: Schematics symbol of electrical actuation method




               Electrical actuators include solenoids which create a magnetic field in


               the cylindrical opening inside a coil, drawing in an actuation plunger

               to  create  linear  motion.  Electrical  solenoids  are  used  on  industrial


               machines,  appliances,  vending  machines  and  in  many  areas  of


               transportation  including  automotive  starters,  choking  mechanisms,

               fuel injection systems and safety interlocks.
