Can someone explain the use of a PCB latch relay to lock and unlock the car doors? I have a very cool momentary switch that I would like to use to lock/unlock the car doors. I am adding this feature to a 1970 Triumph TR6. I am very new to electrical work in a car. So a simplified instruction in very layman terms would really help me out.
Also, the PCB latching relay that is refered to in the 12volt.com instruction? Would this relay work?
Small High-Current PC Mount Relay
An inexpensive means of switching loads up to 30 amps. While these small, low-cost relays are designed primarily for the appliance industry and heating, ventilating and air conditioning markets, the are also well suited for automotive load management and other applications.
- Meets UL class F insulation standard
- Electrical life expectancy is 100,000 operations at rated loads
- Mechanical life expectancy is 10 million operations
- Dielectric strength: 1,500Vrms (between contact and coil)
- Contact Form: SPST
- Coil Voltage: 12VDC
- Coil (Ohms): 270
- Contact Voltage: 250VAC
- Contact Current: 12A
- Pins: 5
- Size: 1.1" L x .48"W x 1.0"H
Can the "Single Pulse to lock/Unlock" circuit be modified in this manner to address my locking/unlocking the door locks?
