Car remotes are super handy for drivers today. They let you lock or unlock your car with just one press. But have you ever had your remote go off by mistake in your pocket? This can drain the battery or even unlock your car when you don’t want it to.
That’s where tactile switch actuation force comes in, especially in the 160-400gf range, like in the KEL-A016 from KANGERLE. The right force stops accidental presses, keeping your Automotive Remote Control safe and reliable. In this blog, we’ll explore why tactile switch actuation force is important, how it prevents the “silent killer” of accidental presses, and why the 400gf range is key for car remotes.
What Is Tactile Switch Actuation Force?
Defining Tactile Switch Actuation Force
Tactile switch actuation force is the push needed to make a switch work. It’s measured in gram-force (gf). For Automotive Remote Control devices, this force decides how easy it is to press a button. If it’s too light, the switch might go off by accident. If it’s too heavy, it’s hard to use. The 160-400gf range, as seen in the KEL-A031, is just right. It balances ease of use with protection against accidental presses.
Why 160-400gf Is Perfect
The 160-400gf range is carefully chosen to give great feedback while stopping unwanted presses. Here’s why it works:
- 160gf: Needs a gentle push, good for frequent use, but still stops most accidental presses.
- 400gf: Takes a firm press, great for important tasks like locking a car. It lowers the chance of pocket presses.
- Circuit Design: The KEL-A016 and KEL-A031 use a SPST-NO This means the switch only works when you press it on purpose, making it super reliable.
| Model | Operating Force | Rated Load | Electrical Life | Circuit | Operating Temperature |
| KEL-A016/KEL-A031 | 160-400gf | DC12V 50mA | ≥100,000 cycles | SPST-NO | -10°C to 60°C |
This range makes sure Automotive Remote Control devices are easy to use and safe from accidental presses.
The Silent Killer: Accidental Presses in Car Remotes
Why Accidental Presses Are a Big Deal
Accidental presses aren’t just annoying. They can wear out your remote’s battery. They might even unlock your car when you don’t want it to, which isn’t safe. Cheap switches with low tactile switch actuation force, like under 160gf, are often the problem. For example, a switch with just 100gf can go off with a tiny bump, like from a keychain in your pocket.
How 400gf Stops Mistakes
A tactile switch actuation force of 400gf, needs a strong, on-purpose push. This makes it hard to press by accident. It’s perfect for important functions like locking or unlocking your car. The SPST-NO circuit also helps. It keeps the switch off until you press it on purpose, which makes your remote safer.
The Importance of Touch Feedback
Touch feedback is the “click” you feel when you press a button. A good switch with 400gf gives a clear click without needing too much effort. This is key for Automotive Remote Control devices. You want to know your command, like locking the car, worked. The KEL-A016 and KEL-A031 give a sharp, satisfying click. This makes using your remote feel good and reliable.
Why SPST-NO Circuits Are the Best Choice
Advantages of SPST-NO for Car Remotes
The SPST-NO (Single Pole Single Throw, Normally Open) circuit is a top pick for Automotive Remote Control devices. It’s simple and dependable. The switch only works when you press it, so it doesn’t use power when idle. This is great for:
- Saving Battery: It stops power waste, so your remote lasts longer.
- Stopping Accidental Presses: The circuit stays off until you press it on purpose, matching the 160-400gf force.
- Long Life: With ≥100,000 cycles, as in KANGERLE’s switches, SPST-NOcircuits last through lots of presses.
SPST-NO vs. Other Circuits
| Circuit Type | Description | Pros | Cons |
| SPST-NO | Stays open, closes when pressed | Saves energy, very reliable | Only controls one circuit |
| SPST-NC | Stays closed, opens when pressed | Good for safety systems | Uses power when idle |
| SPDT | One pole, two options | Works for multiple circuits | More complex, costs more |
The SPST-NO design, used in the KEL-A016 and KEL-A031, is perfect for Automotive Remote Control devices. It focuses on stopping accidental presses and saving energy.
Why Key Travel Distance Matters
Balancing Travel and Force
Key travel distance is how far you push a button to make it work. In Automotive Remote Control devices, a short travel distance with a 400gf tactile switch actuation force makes pressing quick and on-purpose. The KEL-A016 and KEL-A031 have just the right travel distance. This makes them easy to use but still precise.
How It Helps Stop Accidental Presses
A short key travel distance with a higher actuation force, like 400gf, lowers the chance of accidental presses. For example, a switch that needs only 0.5mm of travel and 400gf is harder to trigger by mistake than one with 1mm travel and 100gf. This combo is a big part of KANGERLE’s tactile switch designs, ensuring accuracy and dependability.

FAQs: Common Questions About Tactile Switch Actuation Force
Q1: What does tactile switch actuation force mean, and why is it a big deal?
A: Tactile switch actuation force is the push needed to turn on a switch, measured in gram-force (gf). It matters because it controls how easy it is to press a button. A higher force, like 400gf, stops accidental presses. This keeps Automotive Remote Control devices reliable while still giving good touch feedback.
Q2: How does actuation force help with anti-accidental press features?
A: A strong tactile switch actuation force, like 400gf, needs a clear, on-purpose push. This lowers the chance of pressing it by mistake. For Automotive Remote Control devices, this stops battery drain and keeps your car secure.
Q3: What’s the role of touch feedback in tactile switches?
A: Touch feedback is the click you feel when you press a switch. In Automotive Remote Control devices, it shows your command, like locking the car, worked. Switches with 160-400gf give clear feedback while preventing accidental presses.
Q4: How does key travel distance change switch performance?
A: Key travel distance is how far a button moves to work. A short distance with the right tactile switch actuation force makes presses quick and on-purpose. This cuts down on accidental presses while keeping the switch easy to use.
Q5: Why is 400gf better than lower actuation forces?
A: A 400gf tactile switch actuation force needs a firm push, which stops accidental presses better than lower forces like 100gf. It’s great for Automotive Remote Control devices, ensuring safety and saving battery life.
