This industrial 12V pressure switch activates at 70 psi and deactivates at 100 psi, featuring a 1/8-inch MPT port for easy installation into standard pneumatic lines. It’s commonly used to control small air compressors and pneumatic horn applications where a precise pressure threshold is required, providing a simple electrical switch that closes at the 70 psi setpoint and opens again at 100 psi. It operates on 12V DC, enabling straightforward integration with typical automotive or workshop power systems. The 70–100 psi operating window offers a defined on/off range for compact pneumatic setups that require a 1/8" MPT connection.
