How To Connect The Toggle Switch

1.Basic Information of the toggle switch

There are four types of the toggle switch:

1.Mini toggle switch (usually with a mounting hole of 6mm or 8mm, mainly used in audio equipment and desk lamps)

2.High current toggle switch (15A or more, usually require a mounting hole of 12mm)

3.The toggle switch with light (with goodHow To Connect The Toggle Switch indication effect)

4.waterproof toggle switch (with waterproof ring inside the switch and water-repellent material outside)

When selecting the toggle switch, it is important to consider the instantaneous current under different current conditions:

In the case of DC, the instantaneous current will be more than three times larger than the normal circuit, and it is generally multiplied by 3.5 to calculate the instantaneous current to prevent the switch from being damaged. The current of the switch that the machine should use can be calculated based on P=UI, where power equals voltage multiplied by current.

Yuling’s self-designed waterproof the toggle switch with light is currently the first domestic enterprise to design such a product. It has different color options, and the tail of the switch is coated with adhesive to increase its waterproof performance. The switch is generally larger and requires a mounting hole of 16mm, making it suitable for use in yachts, modified cars, motorcycles, and automated equipment.

2-pin toggle switches are “ON-OFF” switches, with one side being on and the other side being off. 3-pin switches are divided into two types, “ON-ON” and “ON-OFF-ON”, with the wiring being the same for both types, but only one of the two circuit lines can be used for work at a time, and switches with an OFF mode can achieve that neither of the two circuit lines are working.

The toggle switch generally have the option of plug-in or screw terminals. There are various styles available, such as 2-pin, 4-pin, 3-pin, 6-pin, 9-pin, and 12-pin, which can be selected according to the actual situation. Both plug-in and screw terminals are forms of electrical components used to fix and connect circuits. Plug-in terminals are electrical components that are fixed and connected by inserting them into holes on the circuit board. They usually come in single-row straight, double-row straight, and triple-row straight styles. Plug-in terminals are fixed and connected by inserting them into holes on the circuit board, and are characterized by their simplicity of installation and reliable connections.

The advantage of plug-in terminals is their simplicity of installation and reliable connections, making them suitable for situations where installation is convenient, the size is small, and connections are frequent. The disadvantage of plug-in terminals is their lower connection strength, which makes them unsuitable for situations that require higher connection strength. In addition, since plug-in terminals need to be inserted into holes, they cannot be directly fixed on the circuit board and require other methods to fix the board.

Screw terminals are electrical components that are fixed on the circuit board by screws, and usually come in various types, such as round head, flat head, and semi-circular head. Screw terminals are fixed on the circuit board by screws and can be easily replaced, disassembled, and repaired as needed. They are characterized by their ease of installation and high reliability.

The advantage of screw terminals is their firm connections, replaceability, and ease of disassembly, making them suitable for situations that require reliable connections and easy replacement. The disadvantage of screw terminals is that installation and disassembly require tools such as screwdrivers, which are relatively cumbersome and less versatile than plug-in terminals.

SPST switch: Single Pole Single Throw switch has only one blade and one contact, and can only control the switching of one circuit. It usually has three terminals, and can be used to connect power and load, or to switch between two different circuits.

DPDT switch: Double Pole Double Throw switch has two blades and two contacts, can control the switching of two circuits, and can switch between two positions of the circuits. It usually has six terminals and can be used to switch between two different circuits in two different positions.

2.Preparation of the toggle switch

The toggle switch is a commonly used electrical component used to control the switch of a circuit, often found in home appliances, electronic devices, machinery, and other fields. Before use, the following aspects need to be considered:

Determine the model and specifications of the switch: Different models and specifications of the toggle switch have different wiring methods, so it is necessary to determine the model and specifications of the switch first in order to correctly wire it.

Determine the function of the switch: The function of the switch needs to be determined according to actual needs, and the corresponding wiring method should be selected.

Determine the voltage and current of the circuit: The voltage and current of the toggle switch should match the circuit. High or low voltage and current can affect the normal operation of the switch and even cause malfunctions.

Connect the wires: During the wiring process, attention should be paid to the correctness of the wiring to ensure that the wires are connected to the correct terminal.

Test the working status of the switch: After the wiring is completed, it is necessary to test the switch to check whether its working status is normal and whether it can control the switch of the circuit.

4.Circuit diagram

The positive terminal of the power source is connected to the common contact C, while the NC and NO contacts are each connected to the wires of a light bulb. The negative terminal of the power source is connected to both wires of the light bulbs.

In normal state, one light bulb is on while the other is off. After toggling the switch, the previously lit bulb turns off and the other bulb turns on.

If a 6-pin toggle switch is used, the wiring method is the same as the 3-pin switch, but the other side can also be connected in the same way to form another set of connections. After wiring, the light bulbs connected to different NO groups have the same working status and are in series, meaning that devices on the same row work together. Devices on different rows are in parallel and do not interfere with each other.
