Switching & Measuring

In this category you will find motion detectors, energy meters and time switches for building technology, energy monitoring and smart automation – from classic surface-mounted individual components to networked smart home solutions. Brands such as Theben, Steinel, Voltcraft, Shelly, Finder and Gossen offer tested quality for private households, commercial enterprises and hobbyists in Switzerland, with fast delivery throughout Switzerland and the Principality of Liechtenstein.

Buy switching & measuring online – for home, garden & commercial use

Whether you want to buy a motion detector online, keep your electricity costs under control with an energy meter or automate processes with a time switch: The range covers proven mechanical solutions as well as digital and smart products. This allows homeowners, tenants, commercial users and hobbyists to quickly find the right component for more comfort, safety and energy efficiency – conveniently from home.

Motion detectors – types and areas of application

Motion detectors are available as infrared models (PIR), high-frequency sensors and dual sensors. Outdoor motion detectors from Steinel and Theben impress with precise detection ranges, adjustable twilight thresholds and weatherproof housings – ideal for driveways, house entrances and patios. Indoor motion detectors and presence detectors are suitable for stairwells, corridors, offices and sanitary areas and can often be coupled with smart home systems. When selecting one, the detection range, type of installation (ceiling/wall) and the desired protection rating (IP) play a central role.

Energy meters and time switches – monitor consumption, automate processes

With energy meters from Voltcraft, Shelly or Gossen, you can identify power guzzlers in your household, document consumption values and specifically exploit savings potential. Time switches from Theben, Finder and Brennenstuhl automate lighting, pumps, electrical devices and seasonal applications such as Christmas lighting or irrigation – digitally programmable or classic analogue with a segment dial. For smart home users, networked models with app control and automation logic are available that allow flexible integration into existing systems.

Who is this category suitable for?

The category is ideal for homeowners and tenants in Switzerland who want to automate lighting, reduce electricity costs and control electrical processes conveniently. Commercial users, electrical installers and building technicians will also find specific components for professional installations and demanding automation projects that are often only available to a limited extent in local specialist retailers.

Quality, safety & product selection

When purchasing switching and measuring products, it is worth paying attention to high switching capacities, robust workmanship and recognised safety features such as CE marking, VDE certification and the appropriate IP protection rating – this way, the components match the intended location of use and operate reliably for years. For permanently installed devices, installation by a qualified electrician is strongly recommended.

Frequently asked questions
What types of motion detectors are there and how do they differ?
There are infrared motion detectors (PIR), high-frequency sensors and dual sensors. PIR models react to temperature differences, high-frequency sensors operate using electromagnetic waves and dual sensors combine both technologies for greater reliability. The choice depends on the location of use and the desired detection properties.
Which energy meters are suitable for home use?
Simple energy metering sockets, intermediate plugs with a display and permanently installed energy monitoring systems are suitable for home use. Voltcraft Energy Logger and Shelly 3EM are popular solutions with which you can record the power consumption, costs and trends of individual devices or circuits.
What is the difference between digital and analogue time switches?
Analogue time switches work mechanically with segments and a dial – they are easy to operate and do not require a power connection for programming. Digital time switches offer more flexibility with weekday programs, random function and astro mode, but require initial programming. Theben offers both variants in proven quality.
How do I install a motion detector safely?
Installation should generally be carried out by a qualified electrician, as work on the power grid can be life-threatening. It is important to ensure a de-energised state during installation, the correct mounting height (often 2 to 3 metres), consideration of the detection range and attention to the protection rating (IP), especially for outdoor applications.
Can I really save electricity costs with energy meters?
Yes, energy meters help to identify hidden power guzzlers, quantify standby consumption and control usage behaviour more consciously. Simply by identifying and switching off devices that run continuously, noticeable savings can be achieved in a typical Swiss household.
Are switching and measuring products suitable for smart home integration?
Many modern products in this category support smart home protocols such as Wi-Fi, Zigbee or KNX. Shelly products and smart energy meters in particular can be integrated into Apple HomeKit, Google Home or custom control solutions, allowing you to automate switching operations and retrieve consumption data on your mobile device.
What should I look for when choosing a time switch?
Pay attention to the maximum switching capacity (watts/amps), the desired time setting (daily/weekly), the number of switching times per day, the type of installation (socket, intermediate plug or DIN rail) and special functions such as astro program, random function or power reserve in the event of a power failure.
Which products are ideal for beginners in building technology?
For beginners, easy-to-use time switches such as the Theben SUL 181, energy metering sockets from Brennenstuhl or Voltcraft, and motion detectors from Steinel with a clear detection range are suitable. These products can be used easily and yet offer reliable functions for initial automation and measuring projects in the home.
