I claim:
1. A lock of the character described including a casing, cylinder and tumblers, a pair of spaced pins carried by the cylinder but insulated therefrom, said pins extending into the keyway of the cylinder and to a position beyond the periphery of the cylinder, an insulated contact continually engaging one of said pins, an insulated contact positioned in theV path of movement of the other of said pins, and a key of insulating material formed with a pair of electrically connected contacts adapted to engage one end of the respective pins carried by the cylinder when the key has been inserted sumciently to rotate the cylinder.
2. In a lock of the character described, a metal cylinder, a casing around the metal cylinder, said casing and said cylinder having coacting tumblers, said cylinder also having a keyway, a pair of contact pins insulated from the cylinder and extending from a point beyond the periphery to a point within said keyway, a resilient contact engaging one of said pins continually, a resilient contact spaced normally from the other contact, and a key having cam portions capable of adjusting said tumblers so that the cylinder may rotate, and a pair ot connected contacts adapted to be brought into contact with said pins when the key has been forced into said keyway sufilciently to cause said tumblers to be moved to such positions that the cylinder may be rotated by the key. I
3.

4. In a lock of the character described, a key formed of insulating material having embedded therein a conductor and a contact block at each end of said conductor, and a coacting lock provided with a cylinder having a pair oi' insulated radially extending pins adapted to engage said blocks when the key is in operative position, and a Contact for each of said pins, one of said contacts being in continuous engagement with one Aof said pins and the other contact being engaged by the other pin only when the cylinder has been turned to an unlocked position.
5. In a lock of the character described, a casing, a cylinder, a key adapted to be inserted into the cylinder, said key having a pair oi' spaced electrically connected blocks, sliding means for connecting one of said blocks with a conductor. and a contact positioned in the path of movement of the other pin for electrically connecting the other pin with a second conductor.
