## Long description

JUNG 539 U 1P is a wired single-pole electrical switch module with a metallic finish designed for basic on/off control in low-voltage installations. The module is rated for 250 V AC and a nominal current of 10 A, and its compact 1-pole construction allows integration into wall-mounted switch systems and electrical panels where a discreet, reliable switching element is needed. Screw terminals accept conductors up to 2.5 mm² and the device can be adapted for different mounting variants and control behaviours.
Advantages
The switch module offers a compact single-pole design with a metallic finish that suits multiple interior styles. Screw-terminal connections provide secure wiring for conductors up to 2.5 mm², enabling straightforward installation and reliable electrical contact. The module can be supplied without claws for alternative fixing methods, and by removing a spring an individual push-button can be converted into a switch, allowing a combined push-button/switch configuration for flexible control options.
Suitable for
 Wall-mounted switch systems in residential and commercial buildings
 Electrical panels requiring a compact single-pole switching element
 Retrofit or new-installation projects where a metallic finish is preferred
 Applications needing screw-terminal connections for up to 2.5 mm² conductors
Key specifications
 Type: single-pole (1P) switch module
 Rated voltage: 250 V AC
 Nominal current: 10 A
 Connection: screw terminals for conductors up to 2.5 mm²
 Finish: metallic
 Convertible control: push-button can be converted to switch by removing a spring
 Mounting variants: available without claw fixings for alternative mounting
How to use
Install the module into the appropriate wall-mounted frame or electrical panel following local electrical codes and disconnect power before work. Connect supply and load conductors to the screw terminals, ensuring conductors do not exceed 2.5 mm² and that connections are tightened securely. If a push-button/switch combination is required, remove the specified spring to convert the push-button into a switch. After wiring, mount the module using the selected fixing method and restore power to test proper on/off operation.
Usage recommendations
Use in dry, indoor environments and avoid exposure to moisture or corrosive atmospheres. Verify that the circuit load does not exceed 10 A and that the line voltage corresponds to 250 V AC. For safety and code compliance, installation and any modifications should be performed by a qualified electrician.
