Any apparatus for opening and closing a circuit is thus termed, but it
is generally applied to automatic apparatus. A typical circuit breaker
is the hammer and anvil of the induction coil. (See Induction Coil;
Anvil.) Again a pendulum connected to one terminal of a circuit may
swing so as to carry a point on its lower end through a globule of
mercury as it swings, which globule is connected to the other terminal.
A great many arrangements of this character have been devised.
