Question:
Which flip flop is used as a push button switch?
Which flip flop is used as a push button switch?
Show Hint
T stands for Toggle.
Whenever repeated switching between 0 and 1 is required, T flip-flops are preferred.

- SR flip flop
- JK flip flop
- D flip flop
- T flip flop
Show Solution

The Correct Option is D
Solution and Explanation
Concept:
A flip-flop is a bistable device capable of storing one bit of information.
Different types of flip-flops include:
• SR Flip-Flop
• JK Flip-Flop
• D Flip-Flop
• T Flip-Flop The T (Toggle) Flip-Flop changes its state whenever a triggering pulse is applied. Because of this toggling behavior, it is widely used with push-button operations.
Step 1: Understand T flip-flop operation.
For a T flip-flop, \[ T=1 \] causes the output to toggle. That is, \[ 0 \rightarrow 1 \] or \[ 1 \rightarrow 0. \]
Step 2: Relate toggling to a push button.
Every time a push button is pressed, a pulse is generated. The T flip-flop changes its state after each pulse. Thus a single button can alternately turn a system ON and OFF.
Step 3: Identify the correct option.
Since push-button operation requires toggling, \[ \boxed{\text{T Flip-Flop}} \] is the appropriate choice. Hence option (D) is correct.
