摘要： A switch assembly comprising a housing, a rigid operating member mounted for movement relative to the housing and accessible to an operator, an electrical contact operable by movement of the operating member from a rest position to an operative position relative to the housing, a flexible seal between the operating member and the electrical contact and capable of transmitting operative movement of the operating member to the contact while preventing passage of moisture and other contaminants from the region of the operating member to the contact, and, a limit preventing movement of the operating member relative to the contact beyond the position at which the contact is operated. The switch can include further operating members and associated contacts and limits carried by the housing and if desired the assembly can incorporate a heater for heating the operating member region of the assembly.

摘要： An upper member of a housing and a plurality of key actuators are unified into a single flat sheet made by stainless steel. The respective ones of the key actuators are made movable by reducing the thickness of the corresponding limited regions of the stainless steel sheet. When a particular one of the key actuators is actuated, a movable contact on a conductive silicon rubber sheet will come into contact with a stationary contact on a circuit board.
