set on release these fuses are very sensitive meaning that very very small movement of lever sets the fuse off. due to small dimensions fuse can be masked and hidden very easy.

tread on umnop-1, and all other special purpose fuses used in yugo army is M10/1 corresponding to treads on all demolition charges like TM-100, TM-200, TM-500, on several frag mines as PMR-1, PMR-2, claymore-like MRUD, and on all secondary fuse fittings on antitank mines from TMM-1 (tellermine 43 copy), TMA-2/3/4/5, TMRP-6.
