WebA normally closed relay will switch power OFF for a circuit when the coil is activated. 5 Pin Relay 5 pin relays provide 2 pins (85 & 86) to control the coil and 3 pins (30, 87 & 87A) which switch power between two circuits. They have both normally open and normally closed connection pins. WebContacts are set up in one of two states, which are normally open (NO) and normally closed (NC). These refer to the state of a contact in a circuit before user input. For example, light switches should be represented as NO contacts, because the circuit is open until a person flips the switch.
WebThe schematic diagram, of course, only shows the circuitry and not the pipe where the switch is physically mounted: This particular flow switch is used to trigger an alarm light if coolant flow through the pipe ever falls to a dangerously low level, and the contacts are normally-closed as evidenced by the closed status in the diagram.
