Abstract: An alarm clock has a housing provided with a control door having a permanent magnet and an actuating rod capable of pushing a conductive elastic piece located in the housing. The conductive elastic piece is capable of actuating a magnetic sensor which is located in the housing and is composed of an electromagnet and a relay capable of altering the polarity of the electromagnet to attract the permanent magnet of the control door. The magnetic sensor is actuated by the control circuit of the alarm clock at a desired time set to buzz such that the polarity of the electromagnet is changed by the relay, and that the control door is thus repelled to remain open.

Abstract: A snooze alarm clock having a housing including a depressible snooze actuator in the housing and movable between an off position and an on position. The clock has a lid hingedly connected to the housing and containing a clock display. The lid has a portion which contacts the snooze actuator in the off position when the lid is in a substantially closed position relative to the housing and which rests lightly on the snooze actuator. The portion of the lid which contacts the snooze actuator depresses the snooze actuator into the on position when the lid is pressed into a fully closed position against the housing.
