<p>The invention relates to interlocking button switch set having smaller sectional width and able to seal its operating panel with elastic thin film cover layer. Said interlocking button switch set formed from a plurality of individual button switch units. In switchover process, the executive end of the starting element in said button switch unit presses down the movable contact arm to cause it rotating round a shaft from one connection position to another connection position, then electrically connecting or disconnecting with one of a pair of static terminals, which is placed respectively at two opposite sides relative to movable terminal. Simultaneously, each button switch unit has only one touch end designed with small traveling distance for implementing switchover conveniently. When buttons are put up at their respective highest position, all of said touch ends still are beneath said cover layer, so that it may be suitable to seal operating panel with cover layer. The invention is compact in configuration, reliable in sealing, suitable to be installed in a small size and compact electrical device, of which the operating panel has to be sealed for using in an occasion being full with dust, oil smoke or/and moisture.</p> |
