2 Million Cycle Lifespan: Tactile Switch Built for the Long Haul
If you’ve ever had a device button wear out too soon, you know how frustrating it can be. That’s why the new TLSM Series Tactile Switches from Littelfuse are making waves. These switches are designed to last—up to 2 million cycles, to be exact. Whether you’re designing equipment for industrial control panels, automotive dashboards, or even medical devices, the TLSM switches are built to handle high-use environments without skipping a beat.
Why Do These Switches Last So Long?
The secret behind the durability of the TLSM Series lies in its compact design and advanced materials. Measuring just 3.45mm in height, these switches pack a punch with their Single Pole Double Throw (SPDT) configuration. Unlike standard tactile switches, which usually offer a single output, the SPDT setup provides two output options. This flexibility makes it possible to build more complex control schemes—think multi-function buttons on EV dashboards or multi-mode controls on medical devices.
Another reason for the longevity is the soft actuator that delivers a precise tactile response without making too much noise. This is especially useful in environments where quiet operation is essential, like in medical diagnostics or consumer electronics.
Built Tough for Harsh Conditions
Not all switches can handle tough environments, but the TLSM Series does. Rated IP54 for dust and water resistance, it can withstand exposure to the elements—perfect for outdoor equipment or factory settings. Plus, it’s designed to operate within a wide voltage range (DC 1V to 16V) and current range (10 µA to 50 mA), making it compatible with low-power applications without sacrificing performance.
Where Will You Find These Super-Durable Switches?
Here’s where the TLSM Series really shines. Its versatility means it can be used across a wide range of applications:
-
Industrial Control Panels: Robust enough for heavy machinery and automation systems where reliability is crucial.
-
Automotive Dashboards: Think about EV charging interfaces and dashboard buttons that get pressed countless times throughout the vehicle’s life.
-
Smart Home Devices: Quiet operation makes it perfect for remote controls and smart switches that blend into living spaces.
-
Medical Equipment: Reliable tactile feedback and longevity are key in wearable devices and portable diagnostic tools.
-
Gaming Controllers: High cycle life ensures that your controller buttons won’t wear out mid-game.
Why It Matters
As products become more connected and automated, switches and buttons are used more frequently—and they need to last. Imagine an EV charging station that’s used hundreds of times a day or a game controller that survives countless button mashes. The TLSM Series is designed for these high-demand scenarios, reducing the need for frequent replacements and maintenance.
The TLSM Series Tactile Switches are now available in tape and reel format, optimized for automated assembly. For engineers looking to integrate these reliable switches into their designs, Littelfuse offers samples through authorized distributors.
