摘要：
A filter head adapted for use with spin-on filters is shown. The filter head carries a spring load piston which is normally biased to close a filter bypass channel. A fluid pressure increase caused by a clogged filter causes the piston to move opening the bypass and at the same time opening a signal channel between a source of fluid pressure and a signal outlet.
