Features

Overview: This item is a Bosch SPST (single-pole, single throw) dual make relay. When 12 volts is delivered to the coil of the relay, the input terminal of the relay makes a connection with two output terminals. Sending current through the relay's coil, allows you to turn on one or more devices without touching them. The relay consists of two parts: the relay, which includes a 5-blade socket, and the 5-blade plug with 5 wires. It has a capacity for up to 30 Amps.

Typical Applications:

  • Relay Turn-On: turning on/off high-current devices such as multiple amplifiers or neon lights using a low current trigger, such as a head unit's amplifier turn on lead
  • Relay Turn-Off: for turning off or disabling a device such as a vehicle's starter system (in conjunction with a security system)
  • Remote Trunk Release: for remote control opening of a vehicle trunk (in conjunction with a security system--requires existing power-assisted trunk release)
  • Power Door Lock System: for remote control locking/unlocking of vehicle doors (in conjunction with a security system and aftermarket power door locks)

Wiring Considerations: Installation of this relay requires splicing or soldering of the connections. Installation of a 30-amp fuse and fuse holder may be required near the battery connection.
