A microminiature SMT tactile switch has been introduced by Schurter Inc. for applications requiring compact dimensions, controlled tactile response, and long operating life. The device measures 4.2 × 3.2 mm with a profile height of 2.5 mm, supporting dense PCB layouts in space-constrained electronic assemblies.
The switch is available with three actuation force configurations: 180 gf, 250 gf, and 400 gf, corresponding to approximately 1.76 N to 3.92 N. These options allow adjustment of tactile response characteristics according to interface and input requirements. Mechanical endurance is rated for up to 100,000 operating cycles.
Electrical ratings support low-power circuit designs with an operating range of 10 µA to 50 mA at 1–12 VDC. Contact resistance is specified at 100 mΩ maximum to maintain consistent electrical performance and signal continuity during operation.
The switch is specified for operation across an ambient temperature range of -40 °C to +90 °C. Intended applications include control interfaces for consumer electronics, home automation equipment, IoT hardware, and medical devices such as blood pressure monitors and ventilators. Typical functions include power control, menu navigation, and parameter selection in compact electronic systems.
