TL3340AF160QG
Overview
The TL3340AF160QG is a subminiature, side-actuated tactile switch designed for space-constrained surface mount applications. It features a right-angle orientation with a 3.40mm actuator length and a 160gf operating force for crisp tactile feedback. This SPST-NO switch is rated for 50mA at 12VDC and utilizes silver-plated contacts for reliable low-voltage switching.
Why Choose This Part
The right-angle, side-actuated design allows for sleek product industrial design by placing the button on the edge of the PCB. With a compact 4.00mm x 3.30mm footprint and gull-wing termination, it provides robust mechanical stability for SMT assembly processes. The 160gf actuation force offers a clear tactile response, improving the user experience for momentary-off switching.
Applications
Key Specifications
Getting Started
When designing the PCB layout, ensure the 4-pin gull-wing pads provide sufficient solder fillets for mechanical strength against side-actuation forces. Designers should verify that the 3.40mm actuator length properly clears the enclosure opening while maintaining the -35C to 85C operating temperature range. SMT reflow profiles should follow E-Switch silver-contact recommendations to prevent tarnishing or flux migration.
