ABSTRACT:
The present invention comprises an armature suspended within a resilient means, wherein the resilient means also performs a capillary function in that a wetting agent, such as mercury, forms a captive reservoir which travels upon said resilient means to said armature and thereby performs a self-renewing wetting function with regard to the contact surfaces of said armature. The armature and resilient means are enclosed within an envelope. The envelope has secured therein one or more contacts which interact with the contact surfaces of the armature (in response to an electromagnetic stimulus) and are continually wetted by said interaction.
