100m Remote Transmitter and Receiver for Winch and Lamps

Question from customer:
I am in need of a controller. I will be using this to control a winch on my pickup and some lights. So I need one button momentary for line in, one button momentary for line out, and 2 buttons on/off for lights.
Answer:
4 Relay multi-mode On / Off remote controller (S4U-DC12 & C-4) is very suitable to you. There are 4 channels for more than one device. It has universal controlling mode, including toggle, momentary, latched, and Momentary+toggle modes. The maximum current is 10A and working distance is about 100m. It features in controlling lights, motors, fans, electrically operated doors / locks / windows / blinds / cars or other appliances with AC110~240V or DC0~28V. You can turn on/off the receiver with transmitter (remote control) from any place within a reliable distance; the wireless RF signal can pass through walls, floors and doors.

According to your requirement, Channel 1~2 are for motor and Channel 3~4 are for lamps. At first, please see the wiring. Wire winch motor to “B” terminals of relay 1 and relay 2. That makes motor rotate in two different directions. Supply power to winch motor. Secondly, wire two lamps to “B” terminals of relay 3 and relay 4. Supply power to lamps.

Thirdly, learning Momentary (Channel 1~2) + Toggle (Channel 3~4) control mode: When the receiver is in the status of LEARNING, press button 3 of the transmitter.
When you press and hold button 1, winch motor rotates in positive direction; release it, winch motor stops.
When you press and hold button 2, winch motor rotates in reverse direction; release it, winch motor stops.
When you press button 3, turn on lamp 1; press button 3 again, turn off lamp 1.
When you press button 4, turn on lamp 2; press button 4again, turn off lamp 2.

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
