An interlocking device for a push-button switch in compact size and with a mechanically simple construction, capable of achieving the interlocking of a push-button switch having a pair of push buttons facing each other and being downwardly movable by pressing in multiple stages, while sufficiently securing the stroke in each stage of the push buttons. The interlocking device is comprised of a first interlocking member and a second interlocking member. The first interlocking member being inserted, at both ends, in the two push buttons respectively, forming a projection at the bottom and being disposed on the switch body swingably and in a way to be movable up and down through a spindle. The second interlocking member being extended, at both ends, to a lower position of the two push buttons respectively, forming, at the top, a projection which comes in contact with the projection formed on the first interlocking member and being swingably provided on the switch body through a spindle.
