An illuminated pushbutton for a pushbutton switch having a light transmitting pushbutton and an indicia cover that is attached to a front end of the light transmitting pushbutton. The indicia cover has non-light transmitting regions and light transmitting regions on its front surface, wherein the light transmitting regions provide visible, light-transmitted indicia on the light transmitting pushbutton. The indicia cover has an adhesive on its rear surface to attach the indicia cover to the front end of the light transmitting pushbutton. An LED in the pushbutton switch is constructed to transmit light to the indicia cover. The light passes through the light transmitting regions (symbols and letters) but not through the non-light transmitting regions. As the light passes through the light transmitting symbols and letters, the symbols and letters are lighted and visible in the dark.

A replay plate 44 is set to have a vertically and horizontally symmetrical shape when a worm wheel 33 is viewed from its axial direction; the worm wheel 33 is provided with an accommodating concave portion 33g in which the relay plate 44 is housed so as to be recessed in the axial direction; and a part of a non-slidably contacting surface in a slidably contacting surface 44a of the relay plate 44, i.e., a non-slidably contacting surface S is covered with first and second fixing parts 35a, 35b that are provided around the accommodating concave portion 33g and protrude in a direction intersecting with an axial direction of the worm wheel 33, the non-slidably contacting surface being a surface with which the contact plate is not slidably contacted.

A switch may include a movable board and a pole board having an inner surface on which a fixed contact point is exposed, the inner surface facing the movable board. A movable contact point may be supported by the movable board and may include a plurality of contact pieces making resilient contact with the inner surface of the pole board. The switch may also include an output terminal corresponding to the fixed contact point. The movable contact point and the fixed contact point may come in contact with each other when a position of the movable contact point is changed via a displacement of the movable board. The fixed contact point and the output terminal may be connected via a board having a disconnection detection circuit. The board may be enclosed in an insulating seal material.

The disclosure provides a flexible pressure switch. A flexible electrode region and a flexible non-electrode region are formed on a flexible printed circuit board at the bottom layer of the flexible pressure switch, two flexible electrodes separated from each other are arranged in the flexible electrode region, a conductive elastic composite body is adhered to and located on the flexible non-electrode region through an elastic adhesion layer, a pressure contact cavity region directly facing the flexible electrode region is formed on the conductive elastic composite body, and an upper surface of the inner wall of the pressure contact cavity region can contact the two flexible electrodes simultaneously or successively so as to switch on the circuit when being pressed. The flexible pressure switch is simple in fabrication process, low in cost, stable in performance and suitable for mass production.
