Abstract: A power strip for use in an anti-theft security system and an anti-theft security system for electrical appliances includes a socket-outlet for receiving a power plug that is electrically connected to a power cord for an electrical appliance. The power strip comprises an electronic circuit configured to measure a first electrical characteristic of the power cord and/or the electrical appliance when the power plug is inserted into the socket-outlet and to measure a second electrical characteristic of the power cord and/or the electrical appliance while the power plug is inserted. A change between the first measurement result and the second measurement results in triggering an alarm.

Abstract: A lock that is particularly suitable for locking cabinets, showcases and drawers includes a bolt and a housing having an opening to receive the bolt and having arranged therein a locking member for locking the bolt. The bolt comprises an bolt body, a chamfered head end and a recess part on the elongated bolt body behind the chamfered head end. The locking member is rotatably provided inside the housing and arranged to rotate between a first orientation to lock the bolt and a second orientation different from the first orientation to release the lock. The locking member comprises a bended first end that fits behind the recess part of the bolt when the locking member is rotated to the first orientation. A coil can be used to, when provided with a current, generate a magnetic force to tilt the locking member to the second orientation.
