Standard 5 pin (SPDT) relays provide 2 pins (85 & 86) to control the coil and 3 pins (30, 87 & 87A) which switch current flow between two contacts. They have both normally open and normally closed connection pins. When the coil is activated, current will be switched from the normally closed pin (87A) to the normally open pin (86). Example:
This can be used for many applications:
- Wiring up a camera to reverse light trigger.
- Remote output for many aftermarket amplifiers.
-ACC power to devices requiring more current.
