Suttner ST-5 Flow Switch mounts further downstream in pumping system then traditional vacuum switches, thereby minimising potential leak points that can cause vacuum switches to close. It is one of the most proven and reliable Flow Switches in the industry. The reed switch is encased in protective vacuum sealed glass tube eliminating exposure to corrosive cleaning chemicals.

Suttner 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, thereby minimiSing potential leak points that can cause vacuum switches to close. The reed switch is encased in protective vacuum sealed glass tube eliminating exposure to corrosive cleaning chemicals.

Suttner ST-6 Water-Activated Flow Switch mounts further downstream in pumping system then traditional vacuum switches, thereby minimising potential leak points that can cause vacuum switches to close. Its water-flow activated switch controls the on and off of the burner. Although the most popular application is high pressure washing, the flow switch is suitable for other appliances, including carpet cleaning equipment, steam boilers and other types of pumping systems. It is one of the most proven and reliable Flow Switches in the industry. The reed switch is encased in protective vacuum sealed glass tube eliminating exposure to corrosive cleaning chemicals.



Suttner ST-7 Flow Switch Is a real "industry first"! R+M Suttner have taken traditional flow switch design snd totally turned it on it's head by introducing a completely new operating principle. gone are the super sensitive reed contacts, with the problem of limited switching capacity, and in their place is a new robust, vibration resistant, micro-switch with a significantly longer working life. The new design means that in the new ST-7, the electrical and water-hydraulic components of the flow switch are now completely separated giving the ST-7 an impressive ingress protection rating of IP65.
