SWITCH - PRESSURE (OPEN) (JLG JL4360037)

A pressure switch that opens its contacts when a preset pressure threshold is reached is a common component in fluid or pneumatic systems. A failed switch in the open position can prevent a system from activating, leading to a no-start or non-functioning condition. This aftermarket replacement part references the JLG catalog number JL4360037. The switch's mechanical function is to physically separate electrical contacts in response to applied pressure. A realistic failure scenario involves the switch remaining open despite normal pressure, which stops downstream equipment from operating. Verify the serial number or application, then call (562) 693-7748. This part is listed as a switch type, specifically a pressure switch with an open configuration.
