MAGNETIC CONTROL DEVICE FOR TIMEPIECE

摘要

A magnetic control device for a timepiece is provided to reduce a size of the control device by using two magnetic sensors for defining three or four positions of a first magnet. A magnetic control device(1) for a timepiece includes an enclosed tube(3) which includes a blocked end portion inserted into a hole of the timepiece. The other end of the enclosed tube is opened to the outside. A control stem(12) is slidden in the enclosed tube. The control stem includes a magnet(21) which is integrated with the stem in the enclosed tube. An end from the enclosed tube is handled, so that a wearer of the timepiece enables the magnet to possess one of three positions selectively. First and second magnetic sensors(22,23) are arranged inside the timepiece along the enclosed tube. Three combinations of the states of the first and second sensors correspond to three positions of the magnet, respectively.
