RELAY AND ELECTRONIC EQUIPMENT USING THIS

摘要

PROBLEM TO BE SOLVED: To obtain a relay to zero-point control both opening and closing of a contact and an electronic device using the same. SOLUTION: The relay 10 is constituted of a signal generating means 11 to output a zero-point signal b synchronized with zero volt of an alternate current power supply 1, an opening and closing detecting means 13 to detect open and close of the contact 12B and to output an opening and closing signal e, a driving means 12A to drive open and close movement of the contact 12B, and a control means 14 which outputs a control signal d of starting/stopping of driving to the driving means 12A and has a time measuring means 14a to measure the time from open and close of the contact 12B until the next zero-point signal b.
