• 【Application】 Designed to work with water holding tank heater pads or elbow pipe heater pads. Also great for remote switching of RV lights, RV water pumps, etc.
• 【Specifications】 Three options available. Do not exceed the max amps. If the amps exceed this amount, add another switch to the circuit.
• 【Easy Installation】 3-Wire design switch panel. Black wire = IN(+), connect to the positive wire of the 12V DC power. Red wire = OUT(+), connect to the positive wire from the heater pad. White wire = IN(-), connect to the negative wire of the 12V power and heater pad.
• 【Operation】 Turn "ON" the switch when the outside temperature is near freezing. Turn "OFF" the switch when the outside temperature remains above freezing, fluids have been vacated, or the RV is not in use.
• 【Red Indicator Light】 With the built-in red indicator light, you can check if the heater pads are turned on even at night. The red LED light turns on/off with the switch. It only draws 0.027A (0.32W) when turned on, saving your 12V battery power.
