Using this switch is quite simple. Just connect the wires to the 6.4mm spade terminals. Make sure to turn off the power before installation to avoid any electrical hazards. When it comes to maintenance, keep the switch clean and dry. If you notice any signs of damage or if the red neon indicator stops working, it's best to replace the switch. Also, always use it within the rated voltage and current (250VAC, 10Amp) to ensure its long - term performance and safety.
