♦Features
MMS product is MANUALLY operated multi polar changeover switches.
They ensure switching, transfer of sources or transfer of two low voltage circuits on load and their safefy disconnection
Fully visible breaking, 3 stable positions(I,0,11) or overlapping contacts on request(1,1+II,II),and on load changeover switching(AC-22 and AC-23)Manual emergency operation. It widely applies to the time control of the equipments, streetlight, warehouse, farming,heating and TV.
