RELAY, CONTROL CIRCUIT AND CONTROL METHOD OF CONTROL CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a relay capable of operating each of a plurality of contacts at desired timing by driving a single electromagnet.

SOLUTION: A relay KM includes at least a first contact a1 and a second contact a2 for switching over from an open state to a closed state by driving an electromagnet 32. The first contact a1 and the second contact a2 each switch over between the open state and the closed state by moving a movable contact segment 31 relative to a fixed contact segment 30 by means of a power transmission mechanism 21 being movable by driving the electromagnet 32. The relay KM is configured so that after the first contact a1 is brought into the closed state, the second contact a2 is brought into the closed state and after the second contact a2 is brought into the open state, the first contact a1 is brought into the open state by the relative shape of the power transmission mechanism 21 with respect to the fixed contact segments 30 of the first contact a1 and the second contact a2.
