First Claim
1. A security device for controlling the ignition circuit of a vehicle provided with a steering lock having locked and unlocked positions and a starter motor circuit, said device comprising an electrical circuit having:
- a security ignition circuit switch means for opening and closing said ignition circuit, in use of the device, independently of any manually operable ignition circuit switch means;
a steering lock control switch means connectable to said steering lock, in use of the device, and having disabling and non-disabling operating conditions, corresponding respectively to locked and unlocked positions of the steering lock, for respectively disabling and not disabling said vehicle with respect to starting thereof;
a plurality of first switch means actuable by a vehicle user and arranged in a security circuit so that operation of each of said first switch means is necessary in said predetermined sequence to close said security ignition circuit switch means; and
connection means for connection of said electrical circuit to a power supply means; and
an alarm connection means, at least one of said vehicle having an audible warning and/or lighting system connectable to said alarm connection means, and said alarm connection means being connected to a separate alarm means, said alarm connection means being arranged for activation thereof in response to actuation of said first switch means in an incorrect sequence, whereby in use of the device the vehicle can only be started when said first switch means have been actuated in said predetermined sequence and said steering lock has been placed in its unlocked position.

Abstract
A security device for controlling the ignition circuit of a vehicle provided with a steering lock 11. The device comprises an electrical circuit having: a security ignition circuit switch means CO32 for opening and closing said ignition circuit independently of any manually operable ignition circuit switch means; and a steering lock control switch means MS1 connectable to said steering lock 11 and having disabling and non-disabling operating conditions, corresponding respectively to locked and unlocked positions of the steering lock 11, for respectively disabling and not disabling said vehicle with respect to starting thereof. A plurality of user actuable first switch means 3 is arranged so that operation thereof is necessary in a predetermined sequence to close the security ignition circuit switch means CO32. An alarm connection means CO52 is connected to alarm means SIREN and arranged for activation in response to actuation of said first switch means 3 in an incorrect sequence. In use of the device the vehicle can only be started when said first switch means 3 have been actuated in said predetermined sequence and said steering lock 11 has been placed in its unlocked position.
