	TUBULAR PIN TUMBLER LOCK : Encyclopedia Entry
		A tubular pin tumbler lock, also known as Ace lock or "axial pin tumbler lock" or "radial lock", is a variety of pin tumbler lock in which 6-8 pins are arranged in a circular pattern, and the corresponding key is tubular or cylindrical in shape.
		Tubular locks are commonly seen on bicycle locks, computer locks, and a variety of coin-operated devices such as vending machines and coin-operated washing machines.
		Even though the pins are exposed, making them superficially easier to pick, they are designed such that after all pins are manipulated to their shear line, once the plug is rotated 1/6 to 1/8 around, the pins will fall into the next pin's hole, requiring re-picking to continue.

		Pin tumbler lock picking consists of raising the cuts on each pin stack to the shear line, one by one, until the plug turns freely.
		Tubular cylinders typically have four to eight pin tumblers arranged in a circular pattern around the circumference of the plug.

	Multiple operation switch lock (Site not responding. Last check: )
		The tumbler pins 36 thus normally lock the driver sleeve 31 and the spindle 30 against rotational motion relative to the tumbler sleeve 34.
		This contact occurs when the lock spindle has been rotated to such an extent that the edge 42b of the cam stop plate 42 abuts the lock pin 46 and causes the switch button to be depressed, which in turn causes an electrical contact to be established within the microswitch 50.
		This in turn frees the spring leg 43a from the confines of the lock pin 46, and hence the twisting force to which the spring had been subjected because of the clockwise motion of the cam actuator in order to align its flat portion with the flat portion of the lock spindle, is released.

	Lock picking at AllExperts
		Lock picking does not damage the lock, allowing it to be rekeyed for later use - this is especially important with antique locks that would be impossible to replace if destructive entry methods are used.
		Medeco locks do this by requiring the pins to be rotated to a correct position, as well as moved to their correct height.
		Pin tumbler locks are particularly suited to master keying, where each lock in the group can be opened by either a master key, which will open any lock in the group, or a specific change key, which will open only that one lock (or others identical to it).

		http://www.crypto.com/papers/notes/picking/s-2faceandside.jpg Wafer tumbler lock The wafer tumbler is similar in operation to the Pin tumbler, however it uses a series of wafers that must be elevated to a specific height rather than pins.
		The trick is that the bottom surface of the pin (the part that touches the key) is angled (most pins have a rounded bottom surface), this permits a key with an angled pin contact surface to rotate the pin to the desired degree.
		When all the pins are rotated and lifted to the proper orientation the lock will open, these locks are exceptionally hard to bypass non-destructively.

		In this way, you move each pin pair into the correct position until all of the upper pins are pushed completely into the housing and all of the lower pins rest inside the plug.

		With the tubular pin tumbler lock the pis are side by side around the barrel, so you can have a 6-pin lock that is only 3/8 of an inch deep.
		The tubular pin lock is very hard to pick without special training, as when you rotate the lock the pins fall into the next hole around, so you have to pick it again and again, six times before the lock will rotate all the way, as opposed to only once for the conventional lock.
