Abstract
A miniaturized locking type push-button switch capable of being assembled easily, and consisting of an operating unit, a spring urging the operating unit in a direction opposite to the direction in which the operating unit is pressed, a slide element holding movable contact members therein, having a heart-shaped groove and slidingly moved in accordance with the displacement of the operating unit on a member to which fixed contact members are attached, a single-acting pin moving along the heart-shaped groove in accordance with an amount of displacement of the operating unit, and an enclosure in which the above parts are housed. This push-button switch is characterized by a single-acting pin supporting element consisting of a one-piece resilient plate having an inwardly extending tongue in the central portion thereof. The single-acting pin is oscillatably supported on the supporting element to form a single-acting block, which is inserted in the enclosure to be fixed therein. The single-acting pin supporting element can be held by fingers during the assembling of a locking mechanism for the switch, so that a push-button switch assembled excellently with ease even when the dimensions thereof have been much reduced.
