Abstract

A relay is sealed with a sealing compound when the relay housing is in a closed state, thus causing an air cushion to be formed in the inside, with an afterflow of sealing compound into the interior being prevented. Following gelling or curing of the sealing compound, a vent hole is pierced into the relay housing which, if required, may be closed following degassing of the interior space of the relay.
