## Questions & Answers

**Q: when the switch for the control of the relay is no longer closed, and is, open, will the relay coil disengage contacts 30(common)  and 87( NO)?**
A: Yes when the control circuit is disengaged the 30 to 87 connection will be interrupted and the other way around if the control circuit is disengaged/switched off then the 30 to 87a connection will be engaged. So a 5 PIN relay can be used to close or open a second high amp circuit based on a low current control flow. so this relay can be used to switch on high circuit devices or used as a circuit breaker. for example if I want to use it to disengage the battery based on a temperature switch I can use this device in connection with a temp switch to cut off my battery below freezing for example :)

**Q: Can I use a standard 20/40 relay with the 6.3 spades in this socket or will it not make a good contact cause of 30, 87, 87a being larger on the socket**
A: Sorry, I cannot be certain.  You are much better off to use the matching socket for a relay.

**Q: What is a CCEE safety standard? Are these ROHS and CE compliant?**
A: If you have such concerns, working with electrical components, such as relays, is likely not a wise choice.

**Q: hi any body know how to install 4 pins ehdiss relay**
A: The installation steps as below:
85:To be connected to the ground chassis. Serves as the common ground connection to activate and magnetize and internal coil.
86: To be connected to a positive input 12V DC input. This is where a switch connected to a 12V DC input will be connected to on the relay. When power is sent to the relay through pin 86, the circuit is completed with pin 85 connected to a common ground, which activates and magnetizes in the internal coil.
87: Normally open contact, also known as NO. The connection between pin 87 and pin 30 is only made when the internal coil is activated or magnetized, which pin 30 can be connected to either a 12V DC positive input or to the ground chassis.
30: Common contact which can be connected to a 12V DC power input or to the ground chassis depending on the desired application. Pin 30 is always connected with pin 87a until the coil is magnetized, which pin 30 then becomes connected with pin 87
