::: PRESSURE SWITCH :::

DesignFlex PSF100A Series

The ONLY Shock and Vibration Resistant Switches Available Anywhere
For Sensing Pressure, Vacuum and Differential Pressure

PSF100A pressure switches utilize a patented double diaphragm/contact configuration to protect against false actuation due to shock and vibration.

FEATURES
• Shock and vibration resistance
• Lightweight, miniature size
• Extremely fast response time
• Military approval

HOW THE PSF100A WORKS
A.		Normal state, no pressure applied: Both contacts of the double make/double break circuit configuration are open.

B.		No pressure applied, subjected to shock or vibration: The contact arms move together in parallel. Since at least one contact is always open, the circuit cannot close in error.

C.		Pressure applied: Both contacts are closed completing the circuit.
