How to replace old toggle two way switch with new touch two way switch?

"How can I replace the old toggle two-way switch with a new touch two-way switch?" Somebody asked me this question a couple of days ago. I told him it’s so easy to do the job. It’s some simple work rather than complicated wirings. You know why? Well, let me show you the reason here today.

Now please have a look at the following figure. It is the connection diagram for toggle two-way switch. As described below, the live wire is connected to switches, then flow to the light. The other side of the load is then connected to neutral wire. When both Switch1 and Switch2 are at ON position, the lamp will be ON (picture on the left). If Switches1 or Switch2 is at OFF position, the lamp will be OFF (picture on the right).


For the new touch two-way switch, its wiring actually is the same as toggle switch. See the following diagram. Live line is connected to the switches. The other side of the load is then connected to neutral line through the light. If you want to replace toggle two-way switch with touch two-way switch, all you need to do is just changing the switches.


Or you choose another way of wiring, which is a little different from that of toggle switch. This time when one switch is connected with another by communication wire A&B, all other connections can be finished through any one switch.


Take note that when doing the wiring, make sure the power supply is disconnected from the load and the switches.

What is Toggle / Momentary / Latched Modes

Generally there are three working modes for rf remote controls : toggle, momentary, latched. Toggle mode is used most often. Controlling lamp, for example, press the button of remote, turn on the lamp; press the button again, turn off the lamp. Momentary mode can be set to control rolling blind or rolling door. You need to press and hold the button of remote to make the blind or door open/close. Both toggle and momentary mode are motivated by single relay, which means you can work these two modes with single button remote. As regards the latched mode, it is motivated by relay group. For relay group, only one relay will be on at a time, e.g. press remote button A, relay A will be on, and relay B will be off; press remote button B, relay B will be on, and relay A will be off. To be more specific, when you control the lamp by latched mode, you should prepare at least two buttons remote. Press button A, the lamp is on; press button B, the lamp is off.

Difference between traditional two-way switch and new electrical touch two-way switch

Various electrical touch two-way light switch from  https://www.remote-control-switch.com Generally speaking, two-way switch controls one light from two locations: for example, the long hallway could have a switch at each end to control one hall light. Or a large family room that has two entrances could have a switch at both entrances to operate one overhead light. A two-way switch allows you to turn on the light conveniently when you enter an area rather than stumble through the dark to find the switch. Now we are going to talk about the difference between traditional two-way light switch and new electrical touch two-way switch. First of all, let’s see what are traditional two-way switch and new touch two-way switch. Traditional two-way switch has a single pole double throw configuration (SPDT). Each has a common terminal (COM) with a pole that can be switched between position L1 or L2. As diagram below shows, the live wire is connected to Switch1, and flow to the lamp through L1
