Patent ID: 7082265

Claim:
An electronic device comprising: a terminal; an armature which can contact the terminal; a knob member which moves between a first position and a second position, sliding the armature on the terminal; a first energizing member which energizes the knob member in the direction of the first position; a second energizing member which energizes the knob member in the direction of the second position; a rotation operation member which can move the knob member and can rotate between a third position corresponding to the first position and a fourth position corresponding to the second position; and a plate which has a first and a second arms with elastic deformation properties, wherein the first arm has an arc-shaped portion at end thereof and is elastic deformed to energize the rotation operation member in the direction of the third position when the rotation operation member is located close to the third position; and wherein the second arm has an arc-shaped portion at end thereof and is elastic deformed to energize the rotation operation member in the direction of the fourth position when the rotation operation member is located close to the fourth position.
