Problems solved by technology

[0002] In the actual use of the contact switch, due to the wear and tear of the contacts and shrapnel, the switch may be in the disconnected state when the switch hits the action stroke. This state will cause false movement of the switch during use. The life detection system with a switch can only monitor the number of times the switch is actually turned on and off, but cannot detect the false movement of the switch, and thus cannot accurately reflect the service life of the contact switch

Abstract

The invention provides a service life test system of a contact-type switch and a service life test method. The service life test system of the contact-type switch comprises a tested switch, a drive device, a first counting device and a second counting device, wherein the drive device drives the tested switch to be turned on and off; the first counting device is electrically connected with the drive device to record drive times of the drive device; the second counting device is electrically connected with the tested switch to record switch-on times of the tested switch. The service life test system of the contact-type switch and the service life test method can be used for testing whether the tested switch has a false operation phenomenon and then judges the service life of the switch.

Description

technical field [0001] The invention relates to the technical field of contact switches, in particular to a life detection system and a life detection method of a contact switch. Background technique [0002] In the actual use of the contact switch, due to the wear and tear of the contacts and shrapnel, the switch may be in the disconnected state when the switch hits the action stroke. This state will cause false movement of the switch during use. The life detection system with a switch can only monitor the actual number of times the switch is turned on and off, but cannot detect the false movement of the switch, and thus cannot accurately reflect the service life of the contact switch. Contents of the invention [0003] The invention aims to provide a life detection system and a life detection method of a contact switch, which can detect whether the contact switch has false movement. [0004] In order to achieve the above object, according to one aspect of the present in...
