SPC-140E Mechanical Pressure Switch
Product Description
Canto SPC Pressure switches are very popular and important in plant control and instrumentation，they are used for regulating, monitoring and alarm systems in industrial applications.
With built-in SPDT micro switch, they are mainly used in control circuits and power circuits, so also called pressure control switch, pressure controls or pressure relay.
SPC Pressure switches will make a changeover when pressure rises up to a preset value (RANGE on scale plate), it will reset when pressure falls through a dead band (DIFF on scale plate). It could be used to protect system away from excessively high pressure or too low pressure, depending on wiring method.
The applicable media could be air, water, Freon, hydraulic oils, gases, steam, and etc.
Both positive pressure switch and vacuum pressure switch are available.
mechanical pressure switch is one of the main products of Canto Switches with good price and quality, factory direct sales and factory supply. Our company is a professional supplier and manufacturer in China, with various products on sale and low discounts.

1,"RANGE" on scale plate refers to switching value on pressure rises, it could be“switch on" or“switch off', depending on wiring mode.
2,"DIFF" refers to pressure differential between two“switching value"
3, RANGE - DIFF = switching value on pressure drops
CAUTION : DON'T attempt to twist other built-in screws except wiring, otherwise product shall be INVALID.
Note: due to continuous product improvement, the appearance of the actual product may differ slightly.
