Works as an up-down switch for my venerable Genie passenger elevator for about 6 months, then fails reliably, usually when I'm at 19ft. in the air. Now in the third block in 18 months. The original switch apparently lasted about 20 years. The original is a much heavier unit from the US but has no equivalent in the current Gardner Bender catalogue. So I keep a spare on hand until I have enough bandwidth to find a more reliable replacement. Cheers to low-cost, high-profit overseas production!
