摘要： In a recording and reproducing device for a magnetic disc, a swingable holder fixedly supports a first magnetic head, while a carriage supporting the holder swingably further supports a second magnetic head in a fixed manner. During a head-load time, the first and second magnetic heads are held in contact with the upper and lower surfaces of the magnetic disc at positions opposite to each other thereby to record or reproduce information to or from the magnetic disc. The recording and reproducing device of the above described construction is further improved by providing a damper device in a moving range of the holder so that the damper device can reduce impact when the first and second magnetic heads are brought into contact with the magnetic disc.

摘要： A tact switch (100) includes a top cover (1), an actuator (2), a metal dome (3), a rubber disc (4), a conductive disc (5) and a housing (6). The housing has four contacts (7) retained therein. The rubber disc is attached to an underside of the metal dome, and the conductive disc is attached to the rubber disc. The metal dome fits into a bottom of the housing with the conductive disc spaced a short distance above the contacts. The actuator is slidably mounted above the metal dome. The top cover is mounted on the housing and includes a plate (11) with a curved lever (12) extending therefrom. The curved lever confronts a ramp (211) of the actuator. In operation, when the actuator is pressed into the housing, the lever of the top cover is forced downwardly by the ramp of the actuator to depress the metal dome, which pushes the conductive disc into electrical connection with the contacts.
