FIELD: electrical engineering.
SUBSTANCE: structure for maintaining the pressure of a moving contact, acting on the moving contact of a dual-power transfer switch, includes a pair of spring holders and a pair of springs; the two corresponding spring holders in said pair of spring holders are positioned in a staggered arrangement; said two spring holders are positioned so that the two springs are installed between the two respective spring holders in parallel; and the moving contact is retained between said two spring holders and said two springs.
EFFECT: stable and reliable operation of a transfer switch due to the maintained stable pressure of the moving contact, and smaller installation space due to the parallel arrangement of the springs.
