Answer:</h2><h3>Reversing switch</h3><h2 /><h2>
Explanation:</h2><h3>A device on a power drill that enables a user to back out a drill bit that is stuck in the work material is called a(n) <u>Reversing switch</u>.</h3>
A power drill is a electrical component that is used to drill or fast screw tightening and it maybe cordless or with cord. So, when the power drill is used to make hole then by using reverse switch it can be back out by rotating in opposite direction.
- It is a simple switch operated electrically.
- It used to reverse the direction in which current is flowing.
- Reversing switch has four terminals.
- These terminals can be connected in such a way that when the switch is triggered then the direction or current is reversed and so the rotation of the motor of the power drill is also reversed.
