Title:
BUTTON SWITCH STRUCTURE OF ELECTRONIC TIMEKEEPER
Document Type and Number:
Japanese Patent JP3232598
Kind Code:
B2
Abstract:
PURPOSE: To provide a button switch structure with good operation feeling and with high reliability in which an electrically conductive path is surely obtained even in an electronic timekeeper composed of a non-conductive member such as plastic and non-metal members.
CONSTITUTION: A switch lever 7 for operating by means of a button 8 and having a resilient part with a projection part close to an edge part, a means transmitting a signal from the outside onto MOS-IC, a circuit block having an electrically conductive part and a metal member with a resilient part corresponding to the conductive part of the circuit block are equipped. An operation feeling is obtained on the resilient part with the projection part close to the edge part of the switch lever 7 according to the actuation of the button 8, a metal member resilient part is pushed with the lever 7 so that a circuit block conductive part and the resilient part of the metal member may come into contact with each other.
