A push-push switch comprises a reciprocatable operation shaft assembled in a housing, a movable contact responsive to operation of the operation shaft, and a heart-shaped cam for locking selectively the operation shaft at a certain position when the operation shaft is pushed in opposition to a recovery spring. An operation spring attached to the heart-shaped cam for pushing the heart-shaped cam toward the operation shaft is made of a plate spring which has two bent hook pieces and a band-like pushing spring portion.
