Paquin is spotlighting our P410 Adjustable Mechanical Pressure Switch, a rugged, configurable plunger type pressure switch for medium to high pressure systems. Built for long life, broad compatibility, and straightforward integration into OEM assemblies.
Built for: demanding mechanical environments across hydraulics, pneumatics, water management, HVAC, automation controls, and equipment/skid builders
Delivers: adjustable setpoints across 435–2,900 psi, SPDT switching, and durability rated at 10⁶ mechanical / 10⁵ electrical cycles
Integrates via: multiple process ports (NPT / SAE / G) and electrical terminations (DIN 43650A, Faston spades, integrated cable) with ingress protection up to IP67
The Problem The P410 Solves
OEM systems and industrial skids often need a simple, reliable way to:
- Trigger alarms or interlocks when pressure reaches a threshold
- Protect pumps/compressors/actuators from out of range pressure
- Standardize a pressure switch platform across multiple builds
The P410 addresses these needs with an adjustable mechanical design, multiple port/termination options, and long life switching.
What’s New / Why It’s Different
-
Three selectable adjustable range bands cover medium to high pressure use cases
-
435–1,450 psi (30–100 bar)
-
725–2,175 psi (50–150 bar)
-
1,450–2,900 psi (100–200 bar)
-
-
Switch point direction choices: set for increasing pressure (R) or decreasing pressure (D) operation
-
Seal/diaphragm options: NBR, FKM, or EPDM for media compatibility
- Broad mechanical integration: multiple process connections including 1/8″ & 1/4″ NPT male, SAE style UNF male ports (SAE 4 / SAE 6), and G thread options (including G 1/4 female); Built to EN 60730 1
Applications
-
Hydraulics & mobile hydraulics: pressure monitoring, pump protection, skid assemblies
-
Pneumatics: pressure threshold switching and control logic
-
Water systems & HVAC: pressure interlocks and equipment protection
-
Automation controls & equipment builders: configurable ports/terminations simplify standardization across builds
