摘要：A moisture proof switch in which an elastomeric O-ring is interposed between a push button and a switch housing. The O-ring is normally held in partial compression to prevent entrance of moisture, etc. into the housing and to normally hold a switch contact member out of engagement with contacts carried by the housing. Depression of the push button further compresses the O-ring to close the switch.
