PURPOSE:To move an external connection terminal for connecting and disconnecting a circuit by forming a terminal plate to be movable through an insulation spring. CONSTITUTION:A surface side terminal plate 2 and a printed wiring board side terminal plate 4 are separated by a coil spring 3, and the surface side terminal plate 2 is not connected with an inner circuit, so direct penetration of static electricity from the surface terminal plate 2 into the inner circuit can be prevented. For exchanging electric signals, etc., with other electronic devices, the surface side terminal plate 2 is pressed to the printed wiring board side terminal plate 4 by a counter contact 9 to be connected with the inner circuit electrically. At this time, a spring pressure P of a counter coil spring 10 is set to be stronger than a spring pressure Q of the coil spring 3 on the electronic device main body side. By using the spring consisting of insulation material, the terminal plate is set movable for switching an external connection terminal. |
