How to Wire Up a Linear Actuator to a Rocker Switch: Step By Step Tutorial

The simplest process to wire a 12v linear actuator to a rocker switch is to use a wiring kit. The installation kit comprises of two wires; red and black wires that are already configured with jumpers to make the connection much easier. Other items in the wiring kit include, the Molex connectors, fuse holders containing fuses, limit switches and diodes.

The installation kit limits the stroke size and extends the length of the wire to be connected to the actuator. These two wires are important because they are used to control the motor of a linear actuator. The connection process can be performed using two options; these include using the momentary rocker switches and non-momentary switches.

Momentary rocker switches aid in extending and retracting the motor. If the button is lowered, the movements stops when pressure is removed from the knob. Using non-momentary switches the linear motor can cause motion in three different positions that is to extend, draw back and help in turning off. To make such connections, the following parts are needed to complete the connection.

The 12 volt mini linear actuator is critical during connection because it operates like a full-size actuator but operates more efficiently. They are ideal where space and weight are of an essence. Mini actuators can be 35 lbs, 50 and 150lbs with different strokes sizes from 1″ to 40″ including a speed of 0.59″sec, 1.18″ sec and 2.00″ sec.

The other parts needed for the connection is the in-line fuse; an in-line fuse contains a fuse holder designed to fit in the in-line fuse. The fuse holder prevents damages caused by power spikes within the unit or in case; the unit is trapped within the application. It is important to ensure that the actuator has full load amperage of a 10A fuse. An additional fuse will be required to make sure that the fuse holder is compatible with the particular type of mini fuse.

The battery helps in power conversion; a good power supply should be reliable and designed for linear actuators, the power sources can be a control box or a mini-tube. Control boxes can convert alternative current to direct current power that can be used in home settings. The control box can be wired or use wireless remote depending on the model type one decides to choose. The power system can either work simultaneously or non-simultaneously to control one or multiple actuators. Control boxes can be connected to a 4pin connector to provide easy wiring setups.

The Molex connector is an important part used during connection because it links the strokes to help the connected wires long enough to reach the motor. A complete wiring kit includes 12 feet of red and black wires, 12-meter Molex connectors, and two fuse holders containing fuses, two lit switches, and two diodes.

Step By Step Instruction

Step 1:

Cut the two wires to ensure that the wires are long enough and can reach the battery. Ensure that the two wires to be joined to the actuator are loose. Fold the Molex connectors, the rocker switch contains specific points to be used to join the wires. The next is to attach both wires to the jumpers in the specific points, then join the same wires to the connection points provide on the opposite side.

Step 2:

The next step in this tutorial on how to wire an actuator is to join the protector to the rocker switch; the same process should also be done on the opposite side. Ensure that the in-line fuse holder fits into the fuse because the holder protects the motor from burning up. The fuse holder stops the motor movement or prevents it from being blocked.

Two in-lines fuse needs to be joined with Molex with leaving two loose wires to be joined to the battery. The actuator needs to be connected to the center with the two fold connectors in terminal three. The in-line fuse should be attached to terminal four sloping towards terminal three. When connecting the second-in-line fuse, the connection process is the same, but the wiring is done on the opposite side.

These two folds wires should be joined on terminal six, with the end of the in-line fuse wire being connected to terminal one.

Step 3:

The last step is to attach the loose wires to the battery, the red wire should be joined to the positive terminal and the black wire connected to the negative terminal so that when pressure is applied to the button, the motor will facilitate backward and forward motion.

After the process is complete, the motor movement will be facilitated by the rocker switch.

The actuator should now be properly controlled by your rocker switch. It is important to test to ensure that the connection is done appropriately. After connecting all the wires, apply + 12 VDC in one of the wires, the movement produced by the motor will be inclined to move in one direction. If the wire is swapped, the actuator movement will move in the opposite direction reversing the polarity; the manual process is the best way to test if the linear actuator works.
