Abstract
Abstract A switch structure suitable for a compact switch device is disclosed. The switch structure is formed of a push button, a switch body switched in correspondence with a pressing operation of the push body and a switch base or a switch holder holding these elements unitary, and a spring member which is elastically deformed in correspondance with the pressing operation of the push button is provided between the push button and the switch body. The switch holder has a fixing member detachably engaged with the switch body for fixing the switch body. The spring member provided between the push button and the switch body makes the pressing stroke longer by the amount of elastic deformation of the spring member. A fixing member provided in the holder fixes surely and easily the switch body in the holder.
