SMD Detector Switch – 4-Pin PCB Switch, 6.5mm Height

Below are the complete specifications for the 4 pin SMD detector switch DS-017 6.5H, covering electrical, mechanical, and environmental ratings.

Specifications are based on the product engineering drawing and should be verified against the latest documentation before production release. Electrical performance depends on the complete detection circuit design.

The DS-017 6.5H is specified for a minimum mechanical life of 50,000 cycles, making it suitable for applications where detection, position sensing, or repeated mechanical triggering is required. This durability ensures reliable performance in equipment that undergoes frequent actuation over its service life.

Designed for repeated mechanical actuation, the switch’s robust construction — featuring beryllium copper contacts with silver plating, PPA housing, and stainless steel spring — supports consistent electrical and mechanical performance throughout its rated life. This makes it a practical choice for position detection, mechanism detection, and mechanical actuation sensing in consumer electronics, portable equipment, and control systems.

The 50,000-cycle specification is derived from the product engineering drawing, providing engineers with a measurable reliability metric for their design validation.

The DS-017 6.5H features a 4-pin configuration that provides duplicated terminal connections within the switch structure. This design supports PCB integration and mechanical stability while providing reliable electrical contact for detection applications.

The 4-pin configuration is arranged with paired terminals that provide redundant contact paths. This arrangement can improve reliability in applications where consistent contact resistance is important. The internal circuit connects the common terminal to the detection contact when the actuator is pressed.

For detailed circuit information and terminal assignments, refer to the product engineering drawing. The electrical pin assignment should be verified against the manufacturer’s documentation before PCB layout.

When integrating the DS-017 6.5H into a PCB design, the recommended mounting dimensions and footprint should be followed for reliable assembly and operation.

Selecting the right SMD detector switch for your application requires consideration of several factors.

1. Mounting Type

SMD (surface mount) supports automated assembly and is suitable for high-volume production. Through-hole provides stronger mechanical retention for manual assembly and prototyping.

2. Number of Terminals

3-pin and 4-pin configurations are common for detector switches. The DS-017 6.5H features a 4-pin configuration with duplicated terminal connections for enhanced PCB retention.

3. Operating Force

Select an operating force that matches your mechanical actuation requirements. The DS-017 6.5H is specified at 50±30gf.

4. Mechanical Life

Choose a switch with a mechanical life rating that meets your application’s expected actuation frequency. The DS-017 6.5H is rated for 50,000 cycles minimum.

What Is an SMD Detector Switch?

An SMD detector switch is a surface-mount component used for position and presence detection in electronic devices. The DS-017 6.5H is a 4-pin SMD detector switch with a compact 5.00 × 4.00 mm footprint and 6.5mm overall height. This detector switch is designed for PCB integration where reliable mechanical detection is required in space-constrained applications.

Detector switches are typically actuated by mechanical components such as lids, doors, trays, or moving parts. When the component moves into position, it contacts the switch’s actuator, triggering the switch to change state. This state change is then read by the device’s controller, enabling the device to respond appropriately.

4 Pin Detector Switch — Configuration and Benefits

A 4 pin detector switch offers several advantages over 2-pin or 3-pin alternatives. The two additional pins provide duplicated terminal connections within the switch structure, supporting PCB integration and mechanical stability. This design improves PCB retention and reliability in high-vibration applications.

The DS-017 6.5H features a 4-pin configuration that provides redundant contact paths. This arrangement can improve reliability in applications where consistent contact resistance is important. The internal circuit connects the common terminal to the detection contact when the actuator is pressed.

50,000-Cycle Mechanical Life — Durability for Repeated Actuation

The DS-017 6.5H is specified for a minimum mechanical life of 50,000 cycles, making it suitable for applications where detection, position sensing, or repeated mechanical triggering is required. This durability ensures reliable performance in equipment that undergoes frequent actuation over its service life.

Designed for repeated mechanical actuation, the switch’s robust construction — featuring beryllium copper contacts with silver plating, PPA housing, and stainless steel spring — supports consistent electrical and mechanical performance throughout its rated life.

PCB Mounting and Footprint Considerations

When integrating this PCB detector switch into a PCB design, engineers should follow the manufacturer’s recommended mounting dimensions and footprint. The compact 5.00 × 4.00 mm footprint allows for efficient board space utilization in high-density PCB layouts.

Key PCB layout considerations include: pad size and placement based on the recommended land pattern, terminal spacing as specified in the engineering drawing, component positioning for proper actuator alignment, and adequate clearance around the switch body for proper operation.

Applications Across Industries

This SMD detector switch is widely used across multiple industries. Position detection applications include detecting mechanical position changes in electronic assemblies. Mechanism detection applications include detecting movement, cover position, or mechanical actuation. Consumer electronics use it for compact detection and switching functions.
