Title:
RELAY, CONTROL CIRCUIT, AND METHOD FOR CONTROLLING CONTROL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2011/129349
Kind Code:
A1
Abstract:
Provided is a relay in which a plurality of contact points are driven by a single electromagnet and can be operated at respective desired timings. The relay (KM) has at least first and second contact points (a1, a2), the states of which are switched from an open state to a close state by the drive of an electromagnet (32). The first and second contact points (a1, a2) switch the states between the open state and the close state by enabling movable contact pieces (31) to move with respect to respective fixed contact pieces (30) by using a power transmission mechanism (21) movable by the drive of the electromagnet (32). By the shape of the power transmission mechanism (21) set relative to the fixed contact pieces (30) of the first and second contact points (a1, a2), the first and second contact points (a1, a2) are set so that the second contact point (a2) is switched to the close state after the first contact point (a1) is switched to the close state and the first contact point (a1) is switched to the open state after the second contact point (a2) is switched to the open state.
