How it works and how to install it
The button is mounted through a 22mm hole in the electrical panel, securing it on panels up to 8.5mm thick. The 4 screw terminals allow for quick cable connection — 3 NO contacts offer versatile configurations for starters and contactors. The key allows locking in the desired position, preventing accidental or unauthorized switching. It operates directly at 240V AC with loads up to 3A in AC-15 mode.
Frequently asked questions
What does NO contact mean and how many contacts does it have?
NO stands for Normally Open — the circuit closes only when the button is pressed. The product has 3 independent NO contacts.
Can I use the button for three-phase equipment?
Yes, the 3 NO contacts allow control of three-phase circuits via contactors or electromagnetic starters.
Does it come with spare keys?
The product comes with 2 keys included in the package for emergency situations or loss.
