| A momentary contact switch suitable for use in an electrical keyboard has cylindrical projections projecting from a baseplate with axial bores into which projections of the keys fit and by which are guided and retained. A resilient boot interposed between each key and the baseplate and surrounding the cylindrical projections bears against the underside of the key to keep its switch unclosed except when force is applied to an actuation surface of the key. A movable contact internal to the boot is transported by actuation of the key to make electrical contact with a fixed contact adjacent the cylindrical projection. In a preferred embodiment the fixed and movable contacts both have the shape of a ring and encircle the cylindrical projection. The movable contact in the preferred embodiment further is formed on a resilient surface of the boot. | ||||||

| A to-be-depressed member includes an elastic dome. A sectional shape of the dome orthogonal to an axis line (X2) of the dome is line-symmetric about a symmetry axis (Ax). The dome has a three-dimensional shape that is symmetric with respect to a virtual plane (Sx) containing the symmetry axis and the axis line. During a swinging movement responsive to a depressing operation, an opposed surface of an opposed member relatively approaches and contacts a distal end of the dome to deform the dome so as to generate a reactive force. As for an angle defined between the axis line of the dome and a normal line (X1) of the opposed surface, the angle (θ0) in an initial state falls in a range from a first angle variation amount from the initial state to a first-contact state to a second angle variation amount from the initial state to a depression-completed state. | ||||||

While the key structure is depressed, the elastic element is pushed by the movable element. The pressure sensing element is pushed by the elastic element according to different magnitudes of the depressing force. Consequently, the key structure generates different pressure sensing signals. | ||||||
