• This is an intermediate relay for controlling a predetermined temperature range in combination with a one-contact or two-contact thermometer. • The current passing through the special circuit (delay circuit and self-holding circuit) of the intermediate relay is a small weak current, which flows to the contact area without sparking, causing fusion of the contact area, and no adhesion of carbon. • Even if a slight vibration is applied to the contact area due to the delay circuit, chattering does not occur during the opening/closing operation.
