Using this pushbutton is easy. Just press it to activate the momentary function for your basic On/Off needs. When connecting, use the small solder lugs to attach the leads properly. Make sure to check the branding on the button to ensure the voltage matches your requirements, as the LED operates between 5 - 12V. For maintenance, since it has an IP65 waterproof rating, it can withstand some exposure to water and dust. But avoid submerging it in water for long periods. Keep it clean by gently wiping it with a dry cloth. If you have any further questions, refer to the datasheet or the product video.
