Description
The Mars 43334 is a single-pole, single-throw (SPST) pressure switch designed to open its contacts when system pressure rises above the set point. This open-on-rise action provides essential safety and control protection in a wide range of HVAC and refrigeration applications, automatically interrupting the circuit when pressure exceeds the desired threshold.
Key Features
- SPST (Single-Pole, Single-Throw) switching configuration
- Open-on-rise operation — contacts open as pressure increases
- Designed for reliable pressure-based circuit control and safety cutout
- Suitable for use in HVAC, refrigeration, and related mechanical systems
- Compact design for straightforward installation in tight spaces
- Mars quality construction for long-lasting, dependable performance
Application
The Mars 43334 pressure switch is ideal for use as a high-pressure safety cutout or system control device. When pressure in the monitored line or vessel rises above the switch’s set point, the SPST contacts open, de-energizing the connected circuit to protect equipment from overpressure conditions. Common applications include compressor protection, refrigeration circuits, and general HVAC pressure monitoring.
