A normally closed relay will switch power off for a. How to use a relay.
Relays Standard
Standard 4 pin relay. Measurements 22 d x 15 w x 25 h. The 95mm wide terminals tend to be used for higher power applications such as for starter motor solenoid activation and the smaller terminals tend to be used for electronics signalling where only very low currents are required. Ii single pole double throw spst such relay has 5 terminal pins which consists of a pair of coil pins a common pin a normally open no pin and a normally closed nc pin. The terminal widths used on 4 and 5 pin relays are almost always 63mm wide however some more specialist relays can have terminal widths of 28mm 48mm and 95mm. Normally open or normally closed. A normally open relay will switch power on for a circuit when the coil is activated.
Copper terminals with aluminum inlay keep electrical resistance low and still provide benefits for wire bonding and corrosion protection. Also when the relay is deactivated from activated state the common pin will conversely break away. Trigger current nominal current. Relay has 2 x 48mm male terminals and 2 x 635mm male terminals. When the relay is not activated the common pin is in contact with the nc pin and when it is activated the common pin will break away from contact with the nc pin and subsequently makes contact with the no pin. Maximum ac load current.
4 pin relay 4 pin relays use 2 pins 85 86 to control the coil and 2 pins 30 87 which switch power on a single circuit.
