Single Tests for Contacts / K. A. Popkov. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2015. № 5. P. 13-18 [Moscow Univ. Mech. Bulletin. Vol. 72, N 2, 2017. P. 208-212].

Problems of operability checking and state diagnosis of N contacts is considered. The test consists in composition of two-pole contact circuits and observation of values produced by these circuits on any value sets of input variables. A break or closing of any single contact is permitted. The goal is to minimize the number of circuits required for operability checking and determination of states of all contacts. Exact values of the minimal possible number of indicated circuits are obtained.

Key words: contact, fault, contact circuit, \pi-circuit, check test, diagnostic test.
