Gewiss GW20511 — Push-Button 1P 250V Ac - No 10A - With Symbol Key - 1 Module - System White
The Gewiss GW20511 is a 1-module, 1P NO push-button switch rated for 250 V ac and 10 A, featuring a white technopolymer body with a key symbol on the button key. Constructed to EN 60669-1 standards, it withstands a test voltage of 2000 V at 50 Hz for 1 minute, maintains an insulation resistance greater than 5 MOhm, and delivers 40,000 prolonged operation position changes at In 250 V ac cosφ=0.6. Screw wiring terminals accommodate solid cables from 0.5 to 2x2.5 mm² and stranded cables from 0.75 to 2x4 mm², with a terminal grip on cable traction exceeding 50 N.

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Gewiss references — within one business day.
