The elastic contact process and stability performance are evaluated through experimental tests performed using a drop hammer. The test results show that the contact time is about 110 \u03bcs and 100 \u03bcs when the threshold acceleration is 480 g and the overload acceleration is 602 g, respectively. The vibration process of the electrodes is explained through an established physical mode. The elastic contact process is analyzed and discussed by Finite Element Analysis (FEA) simulations, which indicated that the contact time is about 65 \u03bcs when the threshold acceleration is 600 g. At the same time, this result also proved that the contact time could be extended effectively by the designed spring stationary electrode. The overload acceleration (800 g) has been applied to the Finite-Element model in ANSYS, the contact process indicated that the proof mass contacted with stationary electrode three times, and there was no bounce phenomenon during contact process, which fully proved that the stable contact process can be realized at high acceleration owing to the designed elastic stationary electrode.<\/jats:p>","DOI":"10.3390\/s18124238","type":"journal-article","created":{"date-parts":[[2018,12,3]],"date-time":"2018-12-03T06:02:09Z","timestamp":1543816929000},"page":"4238","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The Elastic Contact and Stability Analysis of an Inertial Micro-Switch with a Spring Stationary Electrode"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0664-3897","authenticated-orcid":false,"given":"Wenguo","family":"Chen","sequence":"first","affiliation":[{"name":"The School of Information Engineering, Qujing Normal University, Qujing, Yunnan 655000, China"}]},{"given":"Huiying","family":"Wang","sequence":"additional","affiliation":[{"name":"The School of Information Engineering, Qujing Normal University, Qujing, Yunnan 655000, China"}]},{"given":"Dejian","family":"Kong","sequence":"additional","affiliation":[{"name":"The School of Information Engineering, Qujing Normal University, Qujing, Yunnan 655000, China"}]},{"given":"Shulei","family":"Sun","sequence":"additional","affiliation":[{"name":"The School of Mechanical Engineering, Guizhou Institute of Technology, Guiyang, Guizhou 550003, China"}]}],"member":"1968","published-online":{"date-parts":[[2018,12,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"185","DOI":"10.1117\/12.593348","article-title":"Latching shock sensors for health monitoring and quality control","volume":"5717","author":"Whitley","year":"2004","journal-title":"Proc.
