A device for preventing unwanted opening of a locked enclosure includes a lock bolt moveable between a locked position and an unlocked position. A face gear is meshable with and rotatable by the worm gear between locking and unlocking positions when the worm gear is driven in the first and second directions, respectively. A blocker member is rotatable between first and second positions. A biasing member is operatively coupled to the face gear and the blocker member to bias the blocker member in a biasing direction. A sliding member selectively disengages the blocker member to allow the blocker member to rotate in the biasing direction. A lever arm is operatively coupled to the sliding member such that the lever arm is in the disengaged and engageable positions when the sliding member engages the blocker member in the first and second positions, respectively.

An electric lock includes a housing, a keypad module and a lock assembly. The keypad module is arranged on the housing. The keypad module includes a key panel, an electrode pad, a circuit board and a spacer. The key panel is marked with a plurality of key characters. The electrode pad is arranged on an inner side of the key panel, and the electrode pad has a plurality of key electrodes corresponding to the plurality of key characters respectively. The circuit board includes a plurality of key circuits. Each of the key circuits is configured to generate a key signal when contacting a corresponding key electrode. The spacer is configured to form a gap between each of the key circuits and the corresponding key electrode. The lock assembly is electrically connected to the keypad module for performing locking and unlocking operations according to the key signal.
