TPA511GLFS

The C&K TPA511GLFS is a versatile multidirectional SMT navigation switch designed for various electronic devices. It features a momentary action contact arrangement (SP, N.O.) and gullwing terminals suitable for SMT mounting.

This switch operates with a maximum power of 1 VA and a maximum voltage of 24V, handling a maximum DC current of 50mA. The electrical specifications include a dielectric strength of 250 Vrms, an initial contact resistance of 200 mΩ, and an insulation resistance of 100 MΩ at 100 VDC. The bounce time is less than 10 ms.

Mechanically, the TPA511GLFS supports orthogonal 4-direction scanning and vertical push-down selection. The travel to make is 0.35 mm ± 0.15 mm for orthogonal directions and 0.25 mm ± 0.15 mm for push-to-select. Operating forces are 1.8 N ± 0.5 N for scanning and 4.0 N ± 0.8 N for push-to-select, with maximum applied forces of 20N for scanning and 40N for selection.

With a life expectancy of 200,000 operations in each direction for scanning and 200,000 operations for push-to-select, this switch is built for durability. It operates and stores within a temperature range of -40°C to +85°C and has an IP50 rating. The switch is supplied on tape and reels, with 1,000 pieces per reel, and is compatible with infrared reflow soldering processes according to IEC 61760-1. It is RoHS compliant and compatible, available with silver or gold contact materials.
