SIMCO 4009921 Industrial Pressure Switch NSMP

The SIMCO 4009921 NSMP industrial pressure switch is a compact device designed to monitor process pressure and deliver a switching action at a 100 psi setpoint. Identified by part number 4009921 within the NSMP family, this switch provides a simple, mechanical-electrical interface for controlling or signaling when the target pressure is reached. In industrial environments, it serves as a reliable point of pressure detection to trigger downstream control logic, alarms, or safety interlocks without requiring complex electronics. The model’s 100 psi rating communicates the specific pressure level at which the contact state toggles, making it suitable for applications where a discrete pressure threshold must be observed and acted upon by a control system. For procurement, the SIMCO brand and 4009921 NSMP designation ensure you’re selecting an exact configuration to fit into existing panels, interlocks, or automation sequences that rely on a defined pressure threshold.
