Reliable precision switching positions and long life are said to be ensured with MA and MB Series micro-limit switches as a result of them being 100% tested prior to shipment. The MA Series with resistive load ratings up to 16A at 250 vac and motor load ratings up to 4A at 250 vac provides 5 million minimum mechanical cycles. The MB Series with resistive load ratings to 10A at 250 vac and motor load ratings up to 1.5A at 250 vac delivers 10 million cycles.
