Circuit diagram

Capacitor C1 is charged fairly rapidly via R3 and D1, whereupon T2 comes on so that the interior light is switched on. When the door is closed again, T1 conducts and stops the charging of C1. However, the capacitor is discharged fairly slowly via R5, so that T2 is not turned off immediately. This ensures that the interior light remains on for a little while and then goes out slowly. The time delays may be varied quite substantially by altering the values of R3, R5, and C1. Circuit IC2 may be one of many types of n-channel power MOSFET, but it should be able to handle drain-source voltages greater than 50 V. In the proto-type, a BUZ74 is used which can handle D-S voltages of up to 500 V.

connector

Switches and relay.

A switch is a mechanical device for controlling the flow of current in a circuit, switching the current either on or off.

Relay

To transfer electrical power (or stop) across a set of contacts using another source of power. A coil is energized, making it an electromagnet.

Fuses

Car Fuses. Fuses in your car have one purpose--to protect your electrical system in the event of a power surge or short circuit

Fusible links

A fuseable link functions like a fuse but it's part of the wiring harness. It's a section of wire that will melt if too much current passes through it

When this fuse blows, none of the electrical components on the vehicle will operate. If you start adding accessories such as off-road lights and/or a winch, you'll most likely blow the fusible link.

1. CIRCUIT BREAKERwww.bcae1.com/cirbrakr.htm - Di'cache' - SerupaA circuit breaker's function is, like a fuse, to break a circuit path when a predetermined amount of current is passed.

Thermal Circuit Breakers:The diagram below shows the simplified version of a self resetting circuit breaker. In this device, the current flows from the battery terminal, through the bi-metal strip and then to the other terminal. The bi-metal strip is made of two different types of metal which have different coefficients of expansion. This means that one will expand more than the other when the rise in temperature is the same for both pieces. In this case, the two metals are bonded to each other. (now keep in mind that this is a simplified diagram) When the strip heats up from the current flow through it, one type of metal expands more than the other. In this case, the black metal expands more than the red and the strip tends to bend upward and disconnect the contacts. You can see that the metal starts to bend as the current increases. When the temperature reaches a given point, the piece will snap into the open position and the current flow will stop. The bi-metal strip is stamped into a special shape which causes the 'snap' action. This will assure that there is EITHER a solid connection OR a complete disconnect. You can see a similar snap action in the top of some soda cans. If you push down on the top it starts to bend downward. After the pressure reaches a certain point, the top will snap down. If you release the pressure slowly, the top will snap into it's original position. This is what happens when the bi-metal strip cools in the breaker.
