Relays that simply turn the circuit on and off and convert are all control relays. The remote oil/electricity cut-off relay described in this article is a control relay. It is the equivalent of a switch that draws the armature into the circuit by means of a magnetic field, thus driving the contacts to break the normally closed contacts. In this way, it plays the role of changing the control circuit. It is the key to controlling the circuit on and off. Vehicle Relays Appearance and Work Internally How to use the ca...
