Compliance and Restrictions


Rated 3 out of 5 by 1reviewer.
Rated 3 out of 5 by Seal around switch body may fail. The original vacuum switch failed when the seal around the snap switch into the vacuum chamber failed. The replacement switch had a seal which appeared to have gaps too. Adding sealant around the snap switch body has made a more secure seal and hopefully longer life. March 22, 2012
