  • Hybrid relay
    Patent number: 6078491
    Abstract: A hybrid relay with an electromagnetic relay system having at least one coil one core yoke unit, at least one armature which switches contacts and one power semiconductor whose switching path, in combination with the contacts switches the load circuit of the relay wherein the contacts are switched on no-load by offsetting the control of the power semiconductor in time resulting in good heat dissipation and a compact design with few individual parts.
