Relay Switch 101: Everything You Need to Know About Remote Control Technology
Relay Switch devices are not new inventions, but they remain essential for automating and remote controlling of various modern devices. SwitchBot offers “smart” relay switches to help people manage their appliances and devices with ease and efficiency. In this post, you’ll learn everything you need to know about relay switches, especially about SwitchBot Relay Switch devices.
Overview
Relay Switch: What Is It and How Does It Work?
Relay switches are electrically powered devices that act as a bridge by directing the flow of electricity between circuits in a variety of appliances and systems. When they receive a small amount of electricity from outside sources, they effectively turn the circuits on or off from anywhere.
What makes a Relay Switch particularly useful is that it allows you to control and automate your home appliances and devices from far away. You can turn on your TV, start your coffee maker, or open your curtains without physically pressing a button. In addition, relay switches can help improve energy efficiency by ensuring your appliances only run when you want them to.
How a Relay Switch Work
When they receive a low-power signal—which acts like a command—there are two things that could possibly happen:
- They close the circuits. When this happens, the electrical current continues flowing. This allows any connected device or home appliance, such as your TV, to turn on or continue working.
- They open the circuits. When this happens, the flow of electricity stops. This causes any connected device or home appliance to turn off because it no longer receives power.
This ability of a Relay Switch to control the flow of electric current without the need for manual operation makes it valuable in smart home technology. With relay switches, you can easily manage your smart devices using your smartphone or popular voice assistants.
Different Types of Relay Switches
1. Electromagnetic Relays (EMRs)
You’ll commonly find EMRs in cars, home appliances, and industrial machines. They consist of three components: a movable armature, a coil wire, and contacts (switch’s connection points). These relay switches work by creating a magnetic field that moves the armature, which closes or opens the circuit. When the circuit is open, the devices stop working because electricity stops flowing.
2. Solid-State Relays (SSRs)
Unlike electromagnetic relays, solid-state relays don’t use moving parts to control electricity. These switches are often used in applications or devices that require constant and fast switching, such as heaters, HVAC systems, lighting systems, and medical equipment. Some of the main advantages of SSRs include a long lifespan, low energy consumption, resistance to shock or vibration, and quiet operation.
3. Reed Relays
Reed relays consist of two thin metal strips that are usually sealed inside a glass tube that’s filled with an inert gas. When an electromagnetic field is activated, these metal strips move together or apart. This in turn opens or closes the circuit.
Key Features of the SwitchBot Relay Switch
SwitchBot offers two Relay Switch products: the Relay Switch 1PM and the Relay Switch 1. One main difference between the two is that the SwitchBot Relay Switch 1PM supports energy consumption monitoring, while the SwitchBot Relay Switch 1 doesn’t. To help you decide which is a more suitable option for your needs, we’ll walk you through their main features.
Compatible With Matter
Both the SwitchBot Relay Switch 1 and 1PM can work with a wide range of smart home and IoT devices, without the use of a central hub. This includes popular virtual assistants (e.g., Alexa) and smart home platforms (e.g., Apple Home, Google Home, and SmartThings). This feature offers several benefits, including easier setup and straightforward management of smart devices.
Built-in Bluetooth Extender
Boosting the Bluetooth signal allows a Relay Switch to easily control various smart devices from a distance, without frustrating interruptions. The SwitchBot Relay Switch 1PM and the SwitchBot Relay Switch 1 have a built-in Bluetooth extender that’s capable of connecting 10 Bluetooth-enabled SwitchBot devices. In addition, it can increase your device’s Bluetooth range up to 80 meters (around 262 feet).
Makes Devices “Smart”
You don’t always need to spend a ton of money on new smart appliances. All you need is a SwitchBot Relay Switch. The SwitchBot Relay Switch 1PM and the SwitchBot Relay Switch 1 can transform your regular devices and home appliances, such as fans, lights, and heaters, into smart ones in as fast as 10 minutes. No need to replace your switches or do any rewiring.
Energy Usage Tracking
Energy consumption monitoring is an important feature in relay switches for many reasons, such as making it easy for users to detect power-hungry and faulty devices. The SwitchBot Relay Switch 1PM performs this function in real time. Not only that, it offers thorough power consumption reports and cloud storage for a year.
Built-in Safety Features
Both SwitchBot relay switches have built-in safety features. The SwitchBot Relay Switch 1PM improves home safety and ensures dependable performance by preventing overheating and overloads. It also adds an extra layer of protection by having the ability to restore its previous state after a power failure without needing your help.
The SwitchBot Relay Switch 1, on the other hand, actively monitors and prevents overheating. It has a V0-rated flame-retardant casing that’s designed to reduce fire risks in case of overheating and short circuiting.
Multiple Control Options
The SwitchBot Relay Switch 1 gives you different convenient ways to control your devices remotely, such as through Bluetooth, Wi-Fi, and voice commands. You can even set timers for automated tasks, such as starting your coffee maker early in the morning, so your devices operate smoothly around your schedule and make your life easier.
Privacy Protection and Offline Control
No internet? That’s not a problem with the SwitchBot Relay Switch 1. This Relay Switch lets you control your appliances and devices without an internet connection, as it supports Bluetooth connectivity.
Practical Applications of the SwitchBot Relay Switch
You can use the SwitchBot relay switches for many things in your everyday life. Here are some examples:
1. Lighting system: A SwitchBot Relay Switch can be connected to your lighting system, whether it’s for your indoor living spaces or outdoor patio. It not only allows you to turn the lights on or off from a distance, but also automates lighting schedules.
Important: Before working on any lighting system, make sure you’ve switched off the circuit breaker to avoid electrical accidents.
2. Controlling home appliances: These relay switches can be used to upgrade your existing home appliances, so they can be controlled remotely and connected to your smart home system. The SwitchBot Relay Switch 1PM and the SwitchBot Relay Switch 1 are compatible with other SwitchBot products, such as the Lock Pro, Curtain 3, Meter Pro (CO2 Monitor), Bot, Water Leak Detector, Contact Sensor, Motion Sensor, Outdoor Meter, and Blind Tilt.
3. Automating household tasks: Being able to program appliances to function according to your schedule is one of the key strengths of the SwitchBot Relay Switch. This means you can effortlessly control devices using a remote control or by tapping a few buttons on your phone, even when you’re far away from home. Imagine setting your blackout curtains to close at specific times to create a dark environment conducive for sleeping.
4. Energy consumption monitoring: SwitchBot Relay Switch 1PM’s ability to keep track of energy consumption would be useful for identifying power-hungry appliances. You can use this information to change your usage habits to lower your bills over time. It even lets you set timers to ensure you’re not wasting electricity when you’re not using your appliances and devices.
5. Use as a Bluetooth extender: A weak Bluetooth signal can cause a number of issues, such as constant disruptions in device control.
