Washing Machine Test Equipment: NL-KEY-16 Control Panel Key Life Tester Runs 16 Stations Non-Stop

Control panels on washing machines and dishwashers are pressed every single day. Keys that lose their feel, need extra force, or occasionally do not respond are typically discovered only after a large batch has shipped — by which time the tooling, the overlay film and the conductive adhesive are already on the line. Key and PCB switch life has to be exposed early with a quantifiable cycling test.

What the NL-KEY-16 key life tester measures

• 16 independently driven stations with programmable force, travel and frequency
• Membrane switches, tactile switches and PCB keys – make/break reliability
• Contact resistance trend over the full action count
• Automatic counting, failure stop and record
• Optional live load switching to emulate the real control circuit

Applicable standards

GB 4706 series household appliance safety, IEC 60335-1 (household appliances – general safety), GB/T 4288 (household washing machines – performance), IEC 60335-2-7 and IEC 60335-2-5.

Stations and throughput

16 stations run non-stop, so hundreds of thousands of key presses that no operator can complete by hand are finished in a few days.
