Title:
SWITCH
Document Type and Number:
WIPO Patent Application WO/2012/073530
Kind Code:
A1
Abstract:
This switch, which is provided with an operating member that is displaced by coming into contact with an object and operates according to the position of the operating member, is provided with: a mode switching unit (125) for switching between a learning mode and a prediction mode; a position detector (121) for detecting at least a predetermined first position and second position of the operating member (7); a time measurement unit (127) for measuring the time from when the first position is detected to when the second position is detected; a reference time setting unit (131) for setting a reference time on the basis of the time measured in the learning mode; a comparator (133) for comparing the time measured in the prediction mode with the reference time; and a notification unit (135) for providing a warning when the results of the comparison indicate that the time measured in the prediction mode is longer than the reference time. This configuration enables switches that are capable of being used for changes in moving speed due to changes in production lines or objects etc., or that can reliably ascertain delays in the moving speed of operating members over long periods to be provided.
