Abstract
A sealed switch has two switch contacts arranged inside a cavity formed in a molded switch body and the terminal connection for each switch contact are also arranged in respective cavities in the switch body. The switch contacts are sealed by a rigid sheet material that is adhered to the bottom of the switch body and a flexible sheet material that is clamped to the top of the switch body by a spring-like metal element that includes an actuator arm arranged adjacent the moveable one of the two switch contacts. Upon depression of the actuator arm, the flexible sheet material is deformed and a moving force is applied to the moveable switch contact to make a switch connection. The cavities housing the terminal connections are covered by a pierceable insulating material, so that connection pins on a circuit board pass through the insulating material and engage with the terminal connections during mounting of the sealed switch.
