• ★Two wires, the red wire is positive and the black wire is negative. The wire is 80mm long and there are terminal blocks at the end of the wire.
• ★The left and right welding points of the switch can be welded together to realize power on, i.e. spray, without the need to control the switch.
• ★There is waterproof adhesive on the welding points of the wires to prevent circuit breakers, and a silver oxide layer on the surface of the atomizing sheet to protect the coating from oxidation.
• ★The atomizing piece needs to be used together with the circuit board with the same frequency to achieve the ideal spray amount.
• ★High-frequency oscillation, micrometer aperture, large atomization amount, fine mist particles, high spray rate.
