Some key functions of a Pressure Switch in a cotton picker may include:

1. Monitoring hydraulic pressure: The Pressure Switch continuously monitors the pressure levels in the hydraulic system of the cotton picker. If the pressure exceeds or falls below a set threshold, the Pressure Switch can trigger an alarm, warning light, or shut off the system to prevent damage to the hydraulic components.

2. Controlling hydraulic functions: Based on the pressure readings, the Pressure Switch can control the activation or deactivation of hydraulic functions to maintain safe operating conditions and prevent overloading or malfunctions.

3. Preventing system failures: By monitoring hydraulic pressure levels, the Pressure Switch helps to prevent system failures, damage to components, and downtime in the cotton picker. It provides an early warning system for potential issues within the hydraulic system.
