Abstract:
A relay device includes a coil portion, a fixed contact, a spring, a moving contact and a drive circuit. The drive circuit controls the electromagnetic force of the coil portion to be a first electromagnetic force when switching the fixed contact and the moving contact in a contact state to a non-contact state. The drive circuit controls the electromagnetic force of the coil portion to be a second electromagnetic force that is larger than the first electromagnetic force after a lapse of a first time from start of control of the electromagnetic force of the coil portion to be the first electromagnetic force. The drive circuit controls the electromagnetic force of the coil portion to be reduced with time after a lapse of a second time from start of control of the electromagnetic force of the coil portion to be the second electromagnetic force.
