Question 9 of 18
What type of switch is represented by this schematic symbol?
Reveal answerThis is a selector switch of the make-before-break variety.
Notes:Selector switches are very, very common in electrical and electronic circuits, for selecting different machine functions. Make-before-break switches are usually used where it is imperative to maintain continuity through the switch which switching between different positions.
Question 3: but there is a difference! Electricity flows in from positive side, the location impacts the light switch
