A reciprocal switch includes a shell with a stopper located therein, a connecting unit located on two sides of the stopper for generating circuit signals, two conducting units having movable contacts located on two sides of the stopper and engaged with an elastic element, and a displacement unit located between the two conducting units and exposed outside the shell. The displacement unit may be moved when subject to an external force to move the conducting units moving to either side to press the connecting unit on one side to generate circuit signals.
