Abstract
A switch assembly includes a switch housing defining an interior volume, and a switch actuator slidably retained within the switch housing. Travel in a first direction by the switch actuator compresses a resilient dome switch and a hard mechanical stop limits a full extent of return travel by the switch actuator within the switch housing. A resilient retention post, formed in a resilient switch pad that includes the resilient dome switch, for example, has a length terminating in a flanged tip that captures the switch actuator and thereby defines a restricted extent of return travel by the switch actuator. The restricted extent of return travel is less than the full extent of return travel, to prevent the resilient dome switch from springedly urging the switch actuator into contact with the hard mechanical stop.
