SPW-181 (pressure switch)

The switching contact is a pressure switch with two contacts.
In order to withstand high-frequency switching and high-load use, the switching mechanism maintains a constant contact pressure until the moment the circuit is opened by rapid opening operation.

Capacitance
AC 250V 750W

Main material
Pressure receiving part (wetted part)		aluminum die cast
Pressure receiving element (wetted part)		stainless steel bellows
cover		Polypropylene
switch body		Phenolic resin molding
contact		Silver
spring		piano wire stainless steel
fluid		Air, gas, oil, water, etc.

Contact configuration, wiring method

Wiring method Turns 　OFF when pressure rises and turns 　ON when pressure drops to terminals 1 and 2 .

Standard specifications Unit: MPa (kg/cm²)
	Pressure adjustment range (pressure range)	Standard setting	Pressure resistance
A.	0.12 to 1.0 (1.2 to 10)	0.30-0.50 (3.0-5.0)	2.0 (20)
		0.35-0.50 (3.5-5.0)
		0.40-0.55 (4.0-5.5)
		0.50-0.70 (5.0-7.0)
		0.63-0.83 (6.3-8.3)
		0.63-0.88 (6.3-8.8)
		0.73-0.93 (7.3-9.3)
B.	1.0 to 1.5 (10 to 15)	1.15-1.40 (11.5-14.0)	2.5 (25)

As a general rule, the pressure setting is the factory setting. When ordering, please specify the operating pressure value (ON, OFF) and port size .
