Battery Disconnect Keyed & Rotary Switches
Battery disconnect switches and master switches are used to preserve battery life and prevent theft by cutting off the power supply to a battery with the simple turn of a switch or key.

Replacing Your Vehicle Ignition Switch
Vehicle ignition switches can be replaced by a repair shop or can be installed on your own if you feel comfortable with disassembling and reassembling a steering column. The process can be accomplished using only a screwdriver and can be a cost-effective option for those who prefer to perform their own work on their vehicles.
Replacing an ignition switch involves removing the steering wheel and steering column to access the existing ignition switch. This work should be performed with the steering wheel in the center position and the battery disconnected to prevent electric shock. Once the old ignition switch is removed, you insert the new switch and reassemble the steering column and steering wheel, and then test the switch.
