4 pin SMD Detector switch 3.6*4.8

The DS-014 is a SMD detector switch — a 4-pin surface-mount detection switch engineered for applications requiring reliable position sensing in a compact footprint. This 4 pin detector switch is commonly used for detecting the presence or position of mechanical components — lid closure, media insertion, door position, or tray seating — in consumer electronics, office automation equipment, and portable devices.

This PCB mount detector switch features a 3.64mm low-profile design, making it suitable for space-constrained PCB layouts. The 4-pin configuration provides redundant electrical contacts for enhanced reliability, with two contacts for the switching circuit and two mechanical anchor pins for improved PCB retention. The SMT termination supports automated reflow soldering, enabling high-volume production workflows.

Manufactured in an ISO 9001:2015 certified facility, this micro switch detector is fully compliant with RoHS 3 and REACH regulations. Available in tape-and-reel packaging for automated SMT assembly, with OEM customization options for volume orders.

Below are the complete specifications for the SMD detector switch DS-014, covering electrical, mechanical, and environmental ratings.

Specifications should be verified against the latest product drawing and engineering documentation before production release. Electrical performance depends on the complete detection circuit design, including the switch, PCB layout, pull-up/pull-down resistors, and load requirements.

A 4 pin detector switch offers several advantages over 2-pin alternatives. The two additional pins — typically mechanical anchor pins — provide enhanced PCB retention, reducing the risk of solder joint failure under mechanical stress. This is particularly important in applications where the switch is subjected to repeated actuation or vibration.

The DS-014’s 4-pin configuration includes two electrical contacts that form the switching circuit, and two mechanical anchor pins that pass through the PCB for additional stability. This design reduces the strain on the SMT solder joints, improving long-term reliability in high-cycle applications.

For engineers designing products with frequent mechanical actuation — such as lid detection in laptops or tray detection in media players — the 4-pin detector switch provides a reliable solution that balances cost, performance, and mechanical durability.

A PCB mount detector switch requires careful attention to footprint design and component placement. The switch should be positioned so that the actuator aligns correctly with the mechanical component it is detecting — whether a lid, door, tray, or cartridge.

When designing the PCB footprint for this PCB mount detector switch, engineers should consider:

• Actuator alignment: The switch must be positioned so the actuator is contacted by the moving component at the correct point in its travel.
• PCB edge clearance: Allow sufficient clearance for the switch body and actuator movement.
• Pad design: Follow the manufacturer’s recommended land pattern for optimal solder joint reliability.
• Mechanical support: The mechanical anchor pins should have adequate pad size and through-hole clearance.

The switch is only one element of the complete detection circuit. PCB trace routing, pull-up/pull-down resistors, and controller input configuration all affect overall system performance.

When selecting a detector switch for your PCB, understanding the differences between SMT and through-hole mounting is essential.

The DS-014 is an SMT detector switch. Choose this for compact PCB designs and automated assembly. For applications requiring maximum mechanical strength, consider through-hole detector switch options.
