67 series pressure switch with double microswitch

The 67 series pressure switch is specially designed for industrial applications requiring a dual switch output. Thanks to the dual microswitch (SPDT), this pressure switch can control two independent circuits, making it ideal for situations where redundancy, dual signal transmission, or advanced process monitoring is required.

With its anodized aluminum housing and IP67 protection, the 67 series is resistant to dust, moisture, and harsh environmental conditions. The compact design (40×40 mm housing) makes installation in tight spaces easy, while the robust construction ensures a long service life – even in demanding environments such as machine construction, transport, pneumatics, and hydraulics.

In addition, this pressure switch is shock and vibration certified according to CEI EN 61373:2012, category 3, making it suitable for railway and mobile applications.
