The single-pole double-throw switch consists of a moving end and a fixed end. The moving end is the so-called “knife”. It should be connected to the incoming line of the power supply, that is, the end of the incoming call, and generally the end connected to the handle of the switch; the other two The terminals are the two ends of the power output, the so-called fixed terminals, which are connected to the electrical equipment.

Two functions of the single-pole double-throw switch:

One is to control the power output to two devices respectively.

The second is that one device can be controlled for different output forms.

Double open

Double open means that there are two independent switches, which can control two lights separately. Both on and off are on the same switch.

Dual control

Dual control means that two groups of such cooperation can control one lamp without affecting each other. It can be turned on or off on any one of them.

For home decoration, if the switch is not installed properly, it will cause all kinds of troubles in the later use. In serious cases, accidents will occur, so how to connect the two-way switch?

First, turn off all the power circuits and prepare two identical switches; then connect the COM of one switch to the live wire, and the COM of the other switch to the live wire of the electrical appliance; then connect the L1 and L1 of the two switches, L2 and Connect L2, and finally connect the neutral line to the lamp holder.

When decorating, the choice of switch sockets is a very important part, so today I will briefly introduce you to the switch sockets, purchase skills and several good brands, so that you can better decorate and install Switch socket, bring good use effect.

Cassette: The switch sockets are all attached to the cassette (also called the bottom box). In terms of material, the cassette has two materials: plastic and iron. Plastics are generally used for civil housing, and irons are generally used for industrial 3-phase 4-wire. As long as the two products are qualified, there is no problem for household use. Plastics are generally used, iron ones may corrode. The bottom box corresponds to the switch panel in different sizes. Generally, there are 120 type bottom boxes, 86 type bottom boxes, etc. The bottom boxes have different depths, and there are deep bottom boxes and shallow bottom boxes. This is determined according to actual needs.

There are two common types: traditional screw terminals and quick-connect terminals. The latter is more reliable in use, and the wiring is very simple and fast. Even if a non-professional construction worker simply inserts the wire into the terminal hole, the connection is complete, and it will never Fall off. Most of them are now generally quick-connect terminals.

Multi-function sockets mainly refer to three-hole sockets. The plug type specified by our national standard is flat, with two poles and two poles with grounding (commonly known as “3-hole”) plugs. Cylindrical plugs are non-standard products that have been eliminated. But I don’t know why the two holes have round heads, while the three holes do have two flat and round types? According to the specification, I personally think that they should be flat plugs. Multi-function sockets are generally used for computers, and general electrical appliances are rarely used! Multi-function sockets are not safe for children due to their relatively large holes, so the door must be protected.

Strong squeeze method should be used, which can greatly enhance the fit between the clip and the plug, and can also eliminate the worry of heat during long-term use. At the same time, the strong squeeze makes the plug not easy to fall off, which effectively reduces the occurrence of non-human factors.

Single-Gang One-Way Switch

A single-gang one-way switch controls a light or electrical appliance from one location. It is commonly used in standard residential installations.

Single-Gang Two-Way Switch

A pair of single-gang two-way switches allows the same light or electrical appliance to be controlled from two locations. For example, one switch can be installed near the living room or hallway entrance and the other near a seating area, allowing the light to be turned on or off from either location.

In a bedroom, switches can be installed at the entrance and beside the bed to control the main light conveniently.

Remote-control switching is another option. When choosing a system, confirm its compatibility with the connected load, installation requirements, and warranty coverage.
