Abstract

See full text

The present invention provides a fluid-related function device capable of suppressing deformation of a connection member and a case part which may adversely be generated by expansion of fluid stored in a space in which spatters at the time of resistance-welding are trapped. A pressure switch includes a space in which spatters generated at the time of projection-welding are trapped. The space is provided between a joint and a cap member. A communication passage brings inside and outside of the space into communication with each other. The communication passages is formed such that it permits fluid to pass through the communication passages and restrains spatters from passing through the communication passages.
