Works as advertised
I purchased this miniature presser switch to use in my racecar to trigger my Accusump. It works as advertised.

Excellent quality
We have been using these for years in a pump to activate a dialer when pressure drops. Very reliable. Some have been installed for many years. Good quality

rugged and compact vacuum switch
I am using this with a vacuum and it switches at a very repeatable setpoint. Seems dependable and easy to adjust with a vacuum gauge to monitor the trigger point.
