PURPOSE:To provide a control key device having responsiveness at the time of operation and small space around a key section. CONSTITUTION:An upper case 3 has a through-hole 3a, and a spherical dome section 3b is laid in the radial external side of the hole 3a in such a way as projected at the upper side of the case 3. The key section 2 of a pad and a contact point pressing section 4 are connected to each other via the through-hole 3a of the case 3. Also, a slide section 2g in slidable contact with the external surface of the dome section 3b is provided on the reverse side of the key section 2. Furthermore, the section 4 is placed on the conductive section of a conductive elastic member 6, and the upper surface of the section 4 is in contact with the holding section 3b of the case 3 at the reverse side thereof. In addition, the slidable contact section 2g of a key top 2 is formed at a gap (s) from the dome section 3b of the case 3. |
