Once the current has built up to its full level, the contact breaker opens.

It had no distributor either, just a contact breaker system.

No contact breaker is required, so the bells are reliable for long service.

They also make modules for vehicles with two or more sets of contact breakers.

This model had triple contact breaker points making timing adjustment complex.

The troublesome contact breaker ignition was later replaced in 1993.

When the piston was at the right point, the contact breaker opened, breaking the battery current.

The ignition firing sequence begins with the points (or contact breaker) closed.

Power mos electronic ignition provides an alternative to contact breakers.

Contact breakers prevent the projectors from projecting below the 'horizon'.

The distributor shaft has a cam that operates the contact breaker.

Traditional contact breaker ignition systems were used, usually with Marelli distributors.

This system requires only a single contact breaker and single coil to run two cylinders.

The old contact breakers were replaced by electronic ignition (1995 in UK).

There is usually some sort of device that opens and closes the circuit called a contact breaker, points or an ignitor.

This was a simple iron-core inductor, used with a battery and a switch called a contact breaker.

The economy finish was upgraded for 1982 'export' models although the contact breaker points and drum rear brake remained.

When the contact breaker closes, it allows a current from the battery to build up in the primary winding of the ignition coil.

Early magnetos had one coil, with the contact breaker (sparking plug) inside the combustion chamber.

It should be noted that the circuit assumes that both contact breakers interrupt the current for an identical proportion of the cycle.

Originally, every ignition coil system required mechanical contact breaker points, and a capacitor (condensor).

The purpose of the contact breaker is to interrupt the current flowing in the primary circuit of the ignition coil.

The contact breaker is usually mounted on a plate that is able to rotate relative to the camshaft operating it.

When the contact breaker opens the circuit, the magnetic field collapses, causing a high electric voltage in the primary and secondary coils.

It simplifies the mechanical arrangements since there is no distributor drive and the contact breaker cam can be fixed to the crankshaft.

Throwing the contact-breaker caused the overhead lights to flare briefly, and a well-aimed thump on the side of the box made them come back up.
