Using this metal pushbutton is easy. Just press it to activate the basic On/Off function. It's designed for momentary use, so it will return to its original state when you release it. When connecting, use the small solder lugs provided. Make sure to check the button branding to confirm the LED voltage requirement, which is between 5 - 12V. The button can handle up to 3A and 250VAC, so ensure your electrical system is within these limits. Regarding maintenance, thanks to its stainless - steel body and IP65 weatherproof rating, it can withstand tough conditions. But still, try to keep it away from excessive moisture and physical damage. If you have any questions, refer to the datasheet or watch the product video for more guidance.
