ELECTRICAL SHOCK-PREVENTABLE KEY UNIT An electrical shock-preventable key unit has a case for slidably accommodating a key body, a slide plate and an electrical shock preventing system. The slide plate engages with the key body and slides reciprocally to position it in the advanced position or in the retracted position. The electrical shock preventing system comprises a conductive member provided on the case, a resistor for attenuating the current due to static electricity, and a conductive contact piece which comes into contact with the key body in the advanced position, and operates to prevent the user from receiving an electrical shock upon locking or unlocking. |
