12 best key switch
A key switch, in the context of automotive applications, is an essential component of the ignition system in a vehicle. It is a type of electrical switch that is primarily responsible for controlling the flow of electrical current to the various systems within the vehicle, including the starter motor, ignition system, and other essential components. Here are some key points about key switches in automotive systems:
Ignition Control: The primary function of a key switch in a vehicle is to control the ignition system. When the key is turned to the "ON" position, it allows electrical current to flow to the ignition system, which in turn activates the vehicle's electrical components.
Start Position: The key switch typically has multiple positions, including "OFF," "ACC" (Accessory), "ON," and "START." The "START" position engages the starter motor, allowing the engine to crank and start.
Key Authentication: Many modern vehicles use advanced key switch systems that incorporate keyless entry and ignition. These systems use a key fob with a transponder that communicates with the vehicle's computer to authenticate the key's presence and authorization to start the engine.
Security: Key switches are an important part of a vehicle's security system. The ignition key is unique to the vehicle, making it difficult for unauthorized individuals to start the vehicle without the correct key.
Replacement Parts: Over time, key switches may wear out or malfunction. When this happens, it is often necessary to replace the key switch to ensure the reliable operation of the vehicle's ignition system.
Compatibility: When replacing a key switch, it is crucial to ensure that the replacement part is compatible with the make and model of the vehicle. Key switches can vary in design and functionality, so selecting the right one is essential.
Wiring and Connections: Key switches are connected to the vehicle's wiring harness, and they may have multiple wires for different functions. Proper installation and wiring are critical to ensure that the key switch functions correctly.
Maintenance: Like other components in a vehicle, key switches may require periodic maintenance or cleaning to prevent issues such as sticking or electrical contact problems.
Aftermarket Options: There are aftermarket key switches available for vehicles, which can offer additional features or customization options for vehicle owners.
In summary, a key switch is a critical component of an automotive ignition system. It controls the flow of electrical current to various vehicle systems and plays a crucial role in starting the engine. Proper maintenance and replacement, when necessary, are essential to ensure the reliable and secure operation of the vehicle's ignition system.

Question: | Do you have one that is normally closed in the off position? Want to use is as a kill switch |
Answer: | Yes |
Question: | what size hole does this require |
Answer: | 3/4" I think is what I remember |
Question: | What is the rated current draw at 12vdc? note that you can not just extrapolate an ac rating to get the dc rating. dc arcs when switched on or off |
Answer: | I don't know an exact rating, but I use mine to control the power on and off for fairly large lift on the back of my pick up for my wheelchair. The chair ,being electric, is about 250#',s alone plus the weight of the platform. Being concerned about power supply and wife sizing i used a clip on amp meter to find it was drawing 9,amps throuh 8 gauge wire running from the battery directly to lift. I have stayed in the chair to text if the lift would handle all the weight. I am about 165#s more. I did not test the a amps then but I about a 4 min cycle time the switch did not get warm or heated at all. Oh by the way, the key switch is straight in line, no relays or such. I hope this helps. It was a replacement to the switch that's been in the for over 15,years. If I can help you any more let me know. Good luck. |
