The use of flip-flop is more common than flipflop. In addition, Oxford's dictionary redirects flipflop to flip-flop in both UK and US versions.
Definition of flip-flop in English:
- Electronics: A switching circuit which works by changing from one stable state to another, or through an unstable state back to its stable state, in response to a triggering pulse.
The tag info, which is taken from Wikipedia, also says flip-flop.
a flip-flop or latch is a circuit that has two stable states and can be used to store state information.
Flip-flop seems not only the common term, but also the correct one. So, should we change [flipflop] tag to [flip-flop] or do some kind of redirection?
EDIT: The tag is [flip-flop] on Stack Overflow, which is correct.
