(n) :
movable rails which can be used to switch a train from one railway track to another; the two metal surfaces in a
distributor which close or open to allow current to flow or not through the ignition coil. Each surface is called a
point singular (there's usually a moving point which is pushed by the distributor cam and a fixed point which isn't), but they're made together in a unit and serviced or replaced that way and are hence normally called points plural
