Pressure switch - 2-4,5 bar - 1/4" tube outer diameter - normally closed - NC

This pressure switch reacts to a pressure of 0 - 0.5 bar. If this pressure is reached, the electrical contact is closed. It is a normally open (NO) pressure switch. Application is mainly in the water supply to detect the input pressure in front of the device.Technical data: Switch type: NO contactConnection (for water pipe): 1/4" tube outer diameterSwitching capacity: 0.6A 125VDC, 0.3A 250VDC,Cable connection: 4.8mm x 0.8mm flat plug (cable socket)What is a pressure switch?In our case, we are talking about pressure switches that close or open an electrical connection at a certain predefined or set pressure (in this case, water pressure).What is an NC pressure switch?A pressure switch that keeps a connection closed in a pressureless state and opens it only under a certain pressure is called NC or carries this designation.NC stands for normally closed. These pressure switches are suitable for switching off, e.g. relays or pumps, when a certain pressure is reached.What is a NO pressure switch?A pressure switch that keeps a connection open in a depressurised state and closes only under a certain pressure is called NO or carries this designation.NO stands for normally open. These pressure switches are suitable, e.g. for recognising whether a certain pressure is present to activate something else, e.g. an info LED or another process.In addition, there are toggle pressure switches, which can be NO or NC, depending on the assignment (connection).

The pressure switch reacts to a pressure of 1 - 10 bar (maximum pressure can be adjusted stepless). The electrical contact is interrupted (opened) if the pressure is reached. It is a toggle pressure switch, which has the properties of an NC or an NO pressure switch, depending on the assignment (connection). Application is mainly in the ultrapure water segment (permeate), when, e.g. a tap is closed.Technical data:Switch type: toggle switchAdjustment range: 1 to 10 barConnection (for water pipe): 1/4" external threadOverpressure proof up to 300 barSwitching capacity: 4A, 250V Materials: body made of 1.4305 (stainless steel), seal and diaphragm made of FKMTemperature range: -5°C to +120°CSwitching differential: 10 - 30 %Protection class: IP 65 (terminals IP 00)Cable connection: 6.3 mm x 0.8 mm flat plug (cable lug)What is a pressure switch?In our case, we are talking about pressure switches that close or open an electrical connection at a certain predefined or set pressure (in this case, water pressure).What is an NC pressure switch?A pressure switch that keeps a connection closed in a pressureless state and opens it only under a certain pressure is called NC or carries this designation.NC stands for normally closed.

These pressure switches are suitable, for example, for detecting whether a certain pressure is present to activate something else, e.g. info LED or another process.
