The present invention provides a switch capable of reducing the length in the height direction. According to the present invention, there is provided a switch comprising a switch portion having an operating surface and a circuit board having an electrode, wherein the electrode is configured to be capable of detecting an operation on the switch portion, a component mounting surface of the circuit board is arranged nonparallel to the operating surface and the thickness of the circuit board does not exceed the height of the switch portion.

Switch and display device

A mask used in a dual pyroelectric sensor and configured to allow the pyroelectric sensor to accurately detect a movement of a moving object in each of the disposition direction of two pyroelectric elements and a direction perpendicular to the disposition direction. The mask is applied to the sensing surface of the dual pyroelectric sensor to increase the sensitivity with which the pyroelectric sensor detects a moving object. The mask includes a sheet configured to block infrared rays and an aperture pattern including through holes formed in the sheet. The aperture pattern is formed in such a manner that the percentages of the respective infrared-irradiated ranges of the two pyroelectric elements of the pyroelectric sensor vary with a movement of a moving object in each of x- and y-directions.
