Description
The Onspot Pressure Cut Off Switch is another critical component in the Onspot automatic tire chain system. It is an electrical switch that monitors the air pressure in the system and ensures that the Onspot system only operates when there is sufficient air pressure available.
The primary function of the Pressure Cut Off Switch is to prevent the Onspot system from engaging when there is insufficient air pressure, which could potentially interfere with the vehicle’s air brake system or other pneumatic functions. The switch is typically installed in the air supply line, between the Pressure Protection Valve (PPV) and the Onspot system’s air cylinder.
When the air pressure in the supply line meets or exceeds the required threshold, usually around 70-80 psi (4.8-5.5 bar), the switch closes, allowing the electrical circuit to be completed and enabling the Onspot system to be activated. If the air pressure drops below the set threshold, the switch opens, breaking the circuit and preventing the Onspot system from engaging.
In this way, the Pressure Cut Off Switch adds another layer of safety and protection to the overall Onspot automatic tire chain system, ensuring that it only operates when the air pressure conditions are suitable, without compromising the vehicle’s other critical pneumatic functions.
