Abstract
An electronic wristwatch is provided with a touch type contactless switch structure for the purpose of altering the operational mode thereof, which comprises a pair of switch electrodes one being disposed on the viewing window in the engagement relationship with a portion of the operator body and the other being constituted of the enclosure thereof made of electrically conducting material. The one electrode is a film of transparent conductive material and, has an end area leading to the movement accommodated within the interior of the wristwatch. Both of the electrodes are isolated from each other via an electrically non-conducting member of low-melting point glass disposed therebetween which includes an extension overlaying the one electrode at the peripheral portion of the viewing window for allowing for moisture invasion.
