How to Wire Toggle Switch?
A toggle switch is an electrical switch that is turned on or off using a lever or handle that moves back and forth. Toggle power switches and joystick switches are other names for this switch. This switch can be used in any electrical application as they are flexible devices. Since switches are usually manually operated, a toggle switch is essential as a simple switch in many circuits. So how much do you know about the wiring of the toggle switch? Next, ATO will lead you to learn the wiring knowledge of the toggle switch.
Next, take several types of toggle switches as examples.
Wiring method of different types of toggle switch
DPDT toggle switch
Double Pole Double Throw (DPDT) toggle switches are used to make or terminate a connection between two conductors and two different circuits. Six terminals on these switches, terminal 3 and terminal 4 get the necessary power to drive the load on the other terminals (1, 5, 2, and 6). The name of this switch is a four-way or four-position switch.
The DPDT toggle switch is represented by terminals 3 and 4. The power required to drive the load on terminals 1 and 5 and terminals 2 and 6 is supplied to these terminals. Between terminals 1 and 5, terminal 3 is switchable. So if the fan is connected to terminal 1 and the motor is connected to terminal 5, terminal 3 representing the toggle switch can switch between operating the fan and operating the motor. The same goes for terminal 4. Between terminals 2 and 6, terminal 4 can be switched. In this case, if the heater is connected to terminal 2 and the blower is connected to terminal 6, then terminal 4, which acts as a toggle switch, can toggle between the heater and the blower.
The two input switches on the DPDT switch can each be connected to one of the two terminals. Therefore, it is possible to enable two switches to control four different circuits or devices.
The circuit of the DPDT toggle switch is shown below:
DPST toggle switch
DPST means Double Pole Single Throw Switch, which is used to make or terminate a connection between two circuit conductors within a single branch circuit. These switches usually have four terminals and can be used to connect and disconnect two pairs of terminals at the same time.
For example, a 30A toggle switch is used to connect a 240V AC load device (such as a dryer or water heater). The 240V hot lead is immediately connected to both poles, the single throw switch, and the point of load as shown, since no neutral wire is required. The dryer is directly connected to the ground wire. When off, the DPST switch will cut both hot wires. Similarly, when in the ON position, it connects two hot wires.
Single Pole Double Throw Switch
These switches usually have three terminals and are usually used in pairs. Any load must be connected to the first terminal in order to power that particular gadget. In order to power the load on terminals 1 and 3, terminal 2 needs to receive the necessary power, while terminal 3 is used to connect any load and can switch on any device. Therefore, the single pole 2-pin toggle switch can power either of the two circuits. A three-way switch is another name for this type of switch.
The three terminals form a double throw switch and any load can be connected to terminal 1 in order to power a specific device. Also, any load can be connected to terminal 3 to power any device. At this point, the power required to power the load on terminals 1 and 3 is delivered to terminal 2. Therefore, the SPDT switch can operate either of the two circuits. It can switch between two circuits so that various gadgets or circuits can be energized with the flick of a switch.
The circuit of the SPDT toggle switch is shown in the figure below:
We connect the 9-volt DC power supply to terminal 2 of this circuit. A toggle switch on terminal 2 allows us to toggle between terminal 1 and terminal 3. The fan is connected to terminal 1. When the switch is flipped to the left (terminal 1), the DC motor does not work. When the switch is turned to the right (terminal 3), the DC motor is on, but the fan is not working. You can see how we use SPDT switches to control two different circuits or devices. Double-throw switches offer two possibilities.
Single Pole Double Throw Switch
SPST, which stands for Single Pole Single Throw, refers to a device with two terminals such as an input and an output. The main job of this switch is to make or terminate a connection between a wire and a branch. When this switch is open, the circuit is cut off, preventing any current from flowing through the load. When the switch is closed, current flows through the load in a similar fashion.
An SPST toggle switch has only 2 terminals. The input is on terminal 1 and the output is on the other terminal. A simple switch is a function of the SPST switch. They interrupt the circuit, preventing current from reaching the load. The current can move in a closed circuit and drive a load. You can see that the DC motor can be started or stopped for use. The circuit of the SPST toggle switch is shown in the figure below:
LED toggle switch
The illuminated toggle switch operates on 12 volts DC and illuminates to show the status of the circuit. Add some sparkle to your switches and control panels by using these illuminated toggle switches. Led switches consist of a toggle switch with an LED light head and a longer handle. Red, green, and amber are available lighting colors. The connection of the switch is mainly composed of power input, power output, and indicator light ground, which are 1/4-inch push-in terminals. If you pay attention to where your ground, power, and pins are, you shouldn't have any problems.
Advantage of a toggle switch
- The toggle switch is a new generation of photoelectric switch devices manufactured by integrated circuit technology and external device technology, with intelligent functions such as time delay, anti-interference, high reliability, stable working area, and self-diagnosis.
- The toggle switch is to switch the circuit on or off through the handle of the toggle switch, so as to achieve the purpose of switching the circuit. The commonly used varieties of toggle switches are unipolar double position, unipolar three position, bipolar double position, and bipolar three positions, etc. It is generally used in low-voltage circuits and has the characteristics of flexible slider movement and stable and reliable performance.
