Technical explanations for mechanical pressure switches Diaphragm pressure switch NO 2a Piston pressure switch NC 2b What is a mechanical pressure switch? Mechanical pressure switches from SUCO monitor the pressure of liquid or gaseous media, and close or open an electrical circuit on reaching a set threshold. Diaphragm pressure switches SUCO diaphragm pressure switches are used in pressure ranges from 0.1 bar to 100 bar, meaning overpressure safety of 35, 100, 300 / 400 and 600 / 700 bar, depending on the used diaphragm type. Piston pressure switches Pressure ranges from 10 bar to 400 bar can...

Classification of electrical switch functions It has proven useful in many applications to deploy our pressure switches with silver contact rivets ensuring that they are fail safe to 10 mA and 10 V. Variants with gold contacts are available in our catalogue for even lower currents and voltages. Potential-free - galvanically isolated Mechanical pressure switches from SUCO are potential-free, i.e. no auxiliary energy is required. Also, there is no electrical contact between the individual, live parts and the housing. Adjustment range of switching point The pressure range, within which the switching...

Technical explanations for mechanical pressure switches Hysteresis can be set at SUCO in range from approx. 10 % (at end of adjustment range) to 30 % or higher (at start of adjustment range), related to the respective switching point for hex 27 and 30 A/F pressure switches with adjustable hysteresis. Due to their design, pressure switches with an overpressure resistance of 100 bar have smaller hystereses than the series with 300 bar or 400 bar overpressure resistance. Piston pressure switches have a slightly larger hysteresis than diaphragm pressure switches. The specifications in the catalogue...

Conversion table for pressure units Water applications Standard piston switches are not suitable for water applications. Pressure switches in stainless steel with EPDM seal have a special sealing system and can therefore also be used for water with corrosion protection, water mixtures or emulsions. The use of other fl uid mixtures should be clarified with SUCO (e.g. swelling of EPDM sealing could happen by water - oil mixture). Pressure switches with stainless steel housings with EPDM-TW diaphragm, SUCO type „5" are designed for the use of drinking water. Gas applications Our pressure switches...
