Product Line:
Absolute Pressure Switch

Series 4300 Pressure Switches provide accurate and reliable switching over a pressure range of 4 to 250 psia. As an absolute pressure switch, the 4300 Series is hermetically sealed for life and is designed to meet critical MIL-Spec environments including shock, vibration and temperature cycling.

The miniature size configuration with rugged, welded stainless steel construction permits the 4300 Series Pressure Switches to be utilized successfully in those applications where space is critical and where the pressure switches must meet severe MIL-Spec type environments. Extensive cycling tests verify a life rating in excess of 100,000 operations.
