SMD TCS43 momentary tactile switch: microminiature precision in 4.2 × 3.2 mm
High-precision motion control with Bogen Magnetics’ miniaturized sensors
Low-profile switching solution for critical user interfaces that require high reliability in tight spaces.
The design of compact electronic devices presents constant challenges in the integration of physical interfaces. The limited PCB space forces engineers to choose components that ensure robustness and precise tactile feedback without increasing the overall volume of the device. The new Schurter TCS43 SMD tactile switch meets this need with an optimized footprint and technical specifications that guarantee durability in demanding environments.
Technical specifications of the TCS43 switch
The TCS43 stands out for its microminiature form factor of 4.2 x 3.2 mm with a low-profile height of 2.5 mm. This design is optimized for surface-mount technology (SMD) with J-type terminals, facilitating its integration into automated assembly processes.
Regarding its electrical and mechanical parameters, the component offers:
- Switching range: Supports voltages from 1 VDC to 12 VDC and currents from 10 μA to 50 mA, ideal for low-power control signals.
- Tactile response and service life: Guarantees a service life of up to 100,000 cycles. The initial contact resistance is a maximum of 100 mΩ, with a contact bounce equal to or less than 5 ms.
- Actuation forces: Offered in three actuation force configurations to suit different design needs: 180 gf, 250 gf, and 400 gf.
- Mechanical resistance: Features an end stop strength of 30 N for 60 seconds.
- Environmental integrity: The device operates in a temperature range from -40 °C to +90 °C and has an IP40 protection rating.
Applications and Benefits in Electronic Design
Thanks to its dimensions and mechanical characteristics, the TCS43 is a robust option for a wide variety of user interfaces. Its construction, which uses silver-plated phosphor bronze for the terminals and silver-plated stainless steel for the contact, ensures a long operational life.
It is especially effective in:
- Medical equipment: Its reliability is crucial in monitoring devices where input data accuracy is vital.
- Consumer electronics and IoT: It allows for the implementation of on/off functions, menu navigation, or parameter selection in portable or connected devices where space is critical.
- Automation: Its ability to withstand temperatures of up to 90 °C allows for its use in controlled industrial environments.
