The sprung switch in the low-voltage ignition circuit that controls the timing of the spark in the high-voltage circuit. Contact breakers are operated by a cam and are sometimes called "points". Modern systems controlled electronically do not need this feature. Points can be faced with silver, platinum or tungsten which interrupt the primary circuit in the distributor to induce a high-voltage current in the ignition.
