6 pin DIP 2p2t Push switch self-lock
6-Pin DIP 2P2T Push Switch Self-Lock is a through‑hole latching switch that delivers two independent changeover contacts in a standard DIP‑6 footprint. It locks mechanically with each press, holding your selected state without continuous power, making it ideal for mode toggling, signal routing, and power selection in development boards, instrumentation, and compact electronic products.
Product Overview
The 6-Pin DIP 2P2T Push Switch Self-Lock combines a miniature dual‑pole dual‑throw (DPDT) switch mechanism with a convenient push‑on/push‑off latching action. Housed in a standard 6‑pin dual in‑line (DIP) package with 2.54 mm pitch, it solders directly into prototyping breadboards, perfboards, or production PCBs alongside DIP ICs. Each press of the actuator toggles both poles simultaneously between their normally‑closed (NC) and normally‑open (NO) positions, and the switch mechanically holds that state until the next press – no holding current required.
This 2P2T push button switch is widely used when a manual, bistable control is needed for two independent circuits at once. Typical tasks include audio source selection, amplifier gain switching, microcontroller mode jumping, power rail routing, and test equipment range changing. Because it is a DIP self-locking switch, it stays put in high‑vibration environments and provides clear tactile feedback, letting operators know the current state by feel.
Engineers appreciate the latching push button switch DIP format for its easy PCB layout. The 6 pins are arranged in two rows of three, with a common (COM), NC, and NO for each pole. This symmetrical layout simplifies routing and allows the switch to be used with standard DIP‑6 IC sockets for socketed, replaceable designs. The switch is rated for low‑voltage DC signals typical in logic and analog circuits, with contact materials chosen for long life and low contact resistance.

Whether you need a reliable 6 pin tactile switch DIP for a prototype or a production‑ready, washable component for automated assembly, this self‑lock DPDT switch offers a balance of compact size, clear state indication, and robust mechanical life. The actuator extends above the DIP body for easy finger operation, while the through‑hole pins provide strong mechanical anchoring.

Why Engineers Choose This 6-Pin DIP Self-Lock 2P2T Switch
True Bistable Latching Mechanism
Each press mechanically locks the actuator in the alternate position – no continuous coil power needed. The switch stays in its last state even through power cycles, making it perfect for configuration jumpers and power routing that must survive reboots.
Dual‑Pole Synchronous Switching
Two electrically independent single‑pole double‑throw (SPDT) sections operate simultaneously from one button. Route stereo audio channels, differential signal pairs, or separate logic and power lines with a single press.
Standard DIP‑6 Footprint
Fits in a 0.3‑inch wide DIP‑6 IC socket or directly on a 2.54 mm grid. No special PCB layout – treat it like a 6‑pin DIP integrated circuit. Excellent for breadboard prototyping and retrofits.
Gold‑Plated Contacts for Low‑Level Signals
Contact surfaces are optimized for dry‑circuit and low‑current applications. Low and stable contact resistance ensures reliable signal integrity in audio, sensor, and logic circuits over the rated lifetime.
Clearly Defined NC/NO Positions
With the actuator in the up (released) position, COM is connected to NC; pushed down and latched, COM connects to NO. The straightforward pinout and visible button height give immediate visual and tactile status indication.
RoHS Compliant & Washable Options
Lead‑free construction meets global environmental directives. Sealed versions are available to withstand PCB washing processes, making them suitable for both hand assembly and reflow‑compatible production lines.
