Consumer electronics are made in large series and used by non-specialists. A switch must withstand thousands of cycles, a speaker has to fit into a small enclosure and a toy should run for a long time on one set of batteries. That is why the service life of controls, dimensions, power consumption and user safety are decisive in the design.
We have arranged the components according to how the product itself is built: controls, load switching, power supply, sound, connectivity and sensors. You will find parts for home appliances, audio and video equipment, toys and home weather stations.
The first thing a user touches is often the main switch. Marquardt rocker switches for 12(4) A and 250 V AC have IP51 protection and 1-0 positions. Control panels can be completed with MEC Multimec SMD PCB push-buttons measuring 10 × 10 mm with an operating force of 3.5 N. Caps with a diameter of 9.6 mm are available for the buttons. For touch control, a 3.5" Display Visions intelligent TFT display with 480 × 320 resolution can be used.
Heaters, motors or compressors in appliances are switched by TE Connectivity power relays. They have a 12 V DC coil and a 16 A contact for up to 400 V AC, in a PCB-mount version, with some types also offering Faston terminals.
Small devices with USB charging are powered by Sunny wall adapters with a 5 V/2.4 A output and two USB ports. TRACOPOWER LED drivers are designed for LED lighting, for example the flush-mounted TIW 12-112 with an 85 to 264 V AC input and a 12 V/1 A output. The Mean Well SCP 35-12 power supply in a metal housing with a 13.8 V/2.6 A output fits inside larger appliances.
Frequently used toys and remote controls are powered by NiMH rechargeable batteries such as Panasonic AAA cells with 1.2 V and 780 mAh. For sensors and devices that should run for years without a cell change, there are Fanso Li-SOCl2 lithium batteries in AA size with 3.6 V and 2.2 Ah.
Visaton miniature speakers fit into compact devices, for example a type measuring 32 × 32 × 11 mm with a frequency range of 150 to 20,000 Hz. The Visaton EX 60 R 25 W exciter makes a rigid surface, such as the wall of an enclosure, produce sound. For simple audio signals, a Sonitron piezoceramic speaker for 500 to 8000 Hz is sufficient. Neutrik metal XLR connectors complete audio equipment.
Wireless connectivity is added with Wi-Fi modules such as the Espressif ESP32-C3-MINI-1 with Bluetooth 5 and an integrated antenna or the 24 × 16 × 3 mm HopeRF HM-WF8266. A wired connection is possible with the USR IoT SMD Ethernet module.
Weather stations, air purifiers and humidifiers measure several quantities at once. Sensirion SCD41 and SCD30 CO2 sensors are factory calibrated, and the SFA30 module measures formaldehyde, humidity and temperature. Particulate matter from PM1.0 to PM10 is detected by the SPS30 sensor. Humidity and temperature are measured by the SHT40 digital sensor with an I2C interface.
We will advise you on choosing components for a specific product, from controls to power supply. For some products you can request a sample and try it in your prototype. Tell us what you are working on and we will suggest a suitable solution.
