Abstract

Electric lock for use e.g. on automobile door or ignition systems uses key (20) incorporating conductors to complete circuits and energise several electronic commuters (pref. transistors) does not authorise energisation if the incorrect key is used and pref. actuates an alarm in this situation. The lock embodies: a guide (50) rotating within a housing (70) between primary and secondary stations, housing mounted contacts (120) for the formation of the commutative circuit and a locking winding excitable on contact closure and provoking the movement of the locking mechanism between primary and secondary stations. Contact closure is effected by using a key of simple fabrication to move the guide, complete the commutative circuit and excite the solenoid etc. Cylinder mechanisms are obviated.
