M40 1T1R Wireless Light Switch
Discover how easily you can modernize your home lighting. The wireless light switch from Spreest doesn't need batteries — power is generated by clicking the button. The strong 433 MHz signal reaches up to 200 m outdoors and 50 m indoors, without interference from walls or doors.
One button can simultaneously operate any number of lamps, and the receiver remembers up to 10 switches, allowing you to expand your installation whenever you wish.
You can mount it using double-sided tape or two screws, so there's no need for plaster chiseling or new cables, and the waterproof button with a lifespan of 200,000 clicks guarantees hassle-free use for years – from the bathroom to the garden gazebo.
Key features
- Zero batteries, zero costs – micro-kinetic technology powers the panel for ~20 years.
- Range up to 200 m / 50 m – stable 433 MHz signal passes through walls and doors.
- Control from multiple locations – 1 receiver ↔ 10 panels, 1 panel ↔ any number of receivers.
- Instant installation – strong double-sided tape or two screws; no new cables needed.
- Remembers settings – returns to the last state after power loss, no re-pairing required.
- Waterproof and durable – > 200,000 clicks, moisture-resistant casing (e.g., bathroom, gazebo).
- Proven in practice – users praise its simple installation, solid construction, and long range.
Installation possibilities
- Multiple switches — 1 luminaire: ideal for long corridors, stairs, or open living rooms; you can freely add more panels without breaking down walls.
- 1 switch — multiple receivers: with one click, you can illuminate several circuits simultaneously — e.g., the entire yard or LED zones in the garden. Installation involves sliding the receiver between the power supply and the lamp, and then sticking or screwing the panel wherever it's convenient for you.
- 1 switch — 1 luminaire: a quick solution for small rooms (bedroom, study).
Unlimited possibility to expand the set, just purchase additional buttons/receivers available in other offers.

Frequently Asked Questions
Q1: Does the wireless light switch require batteries?
- A1: No, the self-powered switch converts kinetic energy into electrical energy.
Q2: What is the maximum range of the wireless signal?
- A2: The indoor range is 99ft/30m, and the outdoor range is 525ft/160m.
Q3: How many receivers can be controlled by one control panel?
- A3: The control panel can control an unlimited number of receivers.
Q4: Does the controller retain settings after a power failure?
- A4: Yes, it retains settings. After power is restored, there is no need to re-pair the devices.
Q5: What does a self-powered switch mean?
- A5: A kinetic switch uses advanced micro-kinetic technology, converting pressure energy into power for the panel. The lifespan is up to 20 years without the need for batteries.
Q6: Can one switch control 3 receivers (lights in different circuits) simultaneously?
- A6: Yes, one switch can control 3 receivers simultaneously.
Q7: How many switches can be used in one house?
- A7: The number is not specified, but one user reported using 8 switches without problems.
Q8: Can the switch be mounted on the wall with screws?
- A8: Yes, it can. Simply remove the casing, attach the mounting plate to the wall, and then reattach the casing.
Q9: Does the switch need to be used frequently to generate enough kinetic energy?
- A9: The energy needed to power the switch is generated when pressed, so it does not matter how often it is used.
