Uses for SUCO pressure switches PLUS

By July 26, 2022Blog

In general, diesel engines and braking systems can be very susceptible to pressure. This is why an alternative braking method such as the SUCO pressure switch has recently been introduced. Using these switches helps increase the reliability of brake systems by detecting the change in hydraulic pressure that would occur if the brake system lost fluid under normal circumstances and a loss in the fluid was detected.

To properly utilise these pressure switches, they must be installed correctly with high-quality fittings to prevent leaks and other problems. To achieve this level of quality, it is also essential that they are installed at close intervals throughout the engine bay to work correctly with each other.

Uses of SUCO pressure switches PLUS

Mechanical pressure switches- or suction cups, use a vacuum measure on cars and trucks to tell you when your brake pedal is being pressed and bring hydraulic pressure back to the master cylinder to activate the brakes. The brake light switch is, in many cases, dependent on vacuum pressure, so if it fails, it will never activate high-quality brake lights.

The SUCO pressure switches are installed within the fluid system of a vehicle and are placed every two feet on average, with one at the brake master cylinder as well. They act as an indicator for air leaks within the system by sensing how much fluid is in the line before activating. One at a time, if there is an air leak, one of them will cause your brakes to lock up while the rest usually operate.

Compact pressure transmitters- are mounted in line with the master cylinder using a vacuum measurement sensor. These are often used in combination with ABS. 

These work as an indicator by sensing how much air is being pulled into the system through the pedal or release of your brakes. They also act as a backup light switch to ensure that they will operate even if your vacuum lines break. 

Brake pressure switches that rely on hydraulic pressure to activate brakes are strategically placed throughout the engine bay. These can sense pressure loss due to exiting air from exhaust fumes or leaks in connection with brake pedal operation.

Offer high IP protection of up to IP6K9K/IP67.

A high-performance pressure switch can be used if you have high-performance brakes that need more force to activate than a standard system. These rely on applying a vacuum from the pedal or releasing the brakes to start. They are installed backwards into your master cylinder by connecting it with a hose and are easily accessible for servicing and replacement.

These are small enough to fit almost anywhere within your vehicle’s engine bay and can provide an extra layer of protection for airlines, fuel lines, exhausts, and even radiators from damage due to leaks and fast-moving airflow.


The SUCO pressure switches plus aim to provide a mechanism to detect air leaks or loss of hydraulic pressure in your brake system. By using pressurised switches as a backup measure, there is an extra level of protection that can be used if the main brake pedal or the hydraulic system loses hydraulic fluid, and the driver must rely on these switches rather than his central braking system. These work by detecting changes in the amount of pressure within the system, which indicates a potential leak or malfunction.
