This NEW! ST-5 Flow Switch mounts in any position with a free floating magnet configuration.further. It mounts downstream in pumping system than traditional vacuum switches.

The ST-5 Flow Switch mounts further downstream in pumping system than traditional vacuum switches, thereby minimizing potential leak points that can cause vacuum switches to close.

This NEW! ST-505 Flow Switch has a vertical mounting position and free floating brass magnet configuration. It mounts downstream in pumping system than traditional vacuum switches.

The ST-6 Water-Activated Flow Switch mounts further downstream in pumping system than traditional vacuum switches, thereby minimizing potential leak points that can cause vacuum switches to close.
