A keyswitch for a keyboard used with a computer or similar device that has a keytop linked to the base board. A printed circuit board having a contact switch associated with each keytop is associated with the base board. Linking each keytop with the base board is a scissors type guide. A pair of resilient springs are attached to the guide. One of the springs is in continual contact with the base board and: the other spring contacts the contact switch only after the keytop has been depressed a fixed distance thereby closing the contact switch.
