Abstract
A damper is provided for a switch mechanism to prevent overtravel in response to a snap-release of a plunger when it is fully depressed. If no precautions are taken to prevent this type of overtravel, springs which urge the plunger away from its base can provide sufficient force to propel the plunger away from the base with sufficient speed and force to cause the plunger to travel past its intended unactuated position. The present invention utilizes a sloped cam surface which acts as a damper to divert the direction of travel of a cam follower relative to a cam and thereby dissipate the kinetic energy of the plunger, button and moveable components attached to the plunger.
