The mechanical pressure switch is a micro switch action caused by pure mechanical deformation.When the pressure increases, the different sensing pressure components (diaphragm, bellows, piston) will deform and move upward. The upper micro switch is activated by a mechanical structure such as a railing spring to output an electrical signal. This is the principle of the pressure switch.

Pressure switches mainly include normally open type and normally closed type.The main features are: the use of threaded quick connectors or copper pipe welding installation structure, flexible installation, easy to use, no need for special installation and fixation.The plug-in wire connector can be selected by the user at will.Within the pressure range, it is manufactured according to the pressure required by the customer.

The copper pipe pressure switch of this chamfered pagoda head is often used in water pumps, such as small water pumps such as beauty instruments and water purifiers. The copper pipes can also be replaced with corrosion-resistant stainless steel pipes.

S.P.D.T (Single Pole Double Throw): Consists of a normally open, a normally closed contact and a common terminal.

D.P.D.T (Double Pole Double Throw): It consists of a symmetrical left and right common terminal and two sets of normally open and normally closed terminals.

Upper limit-contact (normally open): When the pressure rises to the set value, the contact will act and the circuit will be turned on.

Lower limit-contact (normally closed): When the Yali drops to the set value, the contact will act and the circuit will be turned on.

Upper and lower limit two contact HL: It is a combination of upper limit and lower limit, divided into two types of independent action of two contacts (dual setting, double circuit) and simultaneous action of two contacts (single setting, double circuit).

Upper limit 2 contact: Combining two upper limit forms, divided into two types of independent action of two contacts (dual setting, double circuit) and simultaneous action of two contacts (single setting, double circuit).

Lower limit 2 contacts: Combining two lower limit forms, divided into two types of independent action of two contacts (dual setting, double circuit) and simultaneous action of two contacts (single setting, double circuit)
