Merrill Extra Heavy Duty Pressure Switch, 40-60

Merrill Extra Heavy Duty Pressure Switch, On @ 40psi - Off @ 60psi

The Merrill MPSXHD4060 extra heavy-duty pressure switch outperforms the competition with its extra-large, heavy-duty case for easy wiring. It features heavy brass wire connections securely holding No.4 wire with set screws to prevent slipping and is ideal for higher horsepower pumps. The Merrill MPSXHD4060 pressure switch signals the pump to start when the water system cuts in at 40 psi (factory set) and cuts out at 60 psi (factory set). The MPSXHD4060 is factory set and is a very reliable pressure switch for consistent water pressure management.

• Factory preset to automatically turn the pump on at 40 psi and off at 60 psi
• Brass contacts for better electrical conductivity
• Heavy brass wire connections (hold no.4 wire) with set screws that will not slip off
• ¼” swivel union so switch case does not need to be pivoted to install
• Heavy fiberboard bracket for movement of contacts is much stronger and heat resistant
