The invention provides a pushbutton switch (1) for vending machines, which comprises a light-emitting unit (5) including a light source (2), a first reflecting portion (3) and a second reflecting portion (4). The first reflecting portion (3) has a parabolic reflecting surface defined as having a focus on the light source (2) and a central axis in a direction intersecting an illumination axis of the pushbutton switch for the vending machine. The second reflecting portion (4) is located in a reflecting direction of the first reflecting portion (3) to reflect light from the first reflecting portion (3) in a direction parallel to the illumination axis. The light from the light source is once extended in the horizontal direction about the optical axis at the first reflecting surface and is then pointed in the illumination direction at the second reflecting surface. This allows the light-emitting unit to have a freely determinable emission area and an appropriated number of light sources, thereby solving the subject matter. The switch can be made thin with a wider emission area and configured to hardly cause a crevice in the seal.
