The 4P2T Push Button Switch (also denoted as 4PDT or 4-Pole Double-Throw) is a high-functionality, compact electromechanical switch engineered for applications requiring simultaneous control of up to four independent circuits across two positions. With 12 pins in a through-hole right-angle mounting style, it installs perpendicular to the PCB, saving valuable board space while providing excellent mechanical support and straightforward wave or hand soldering.

This versatile switch offers two operation modes: momentary (contact made only during press, with spring return to default state upon release) and latching (alternate-action push-on/push-off—each press toggles the four poles between their two throw positions, holding the state until the next actuation). The terminal layout maintains a standard 2.5mm pitch, ensuring compatibility with common PCB footprints and easy routing in multi-layer or dense designs.

Electrically rated for DC 50V at 0.3A, it excels in low-power signal switching, logic control, and low-current interfacing rather than heavy loads. Mechanically, it delivers a responsive feel with 3.0mm total travel for clear actuation and 2.0mm lock travel (in latching mode) for positive, tactile confirmation of state changes and reduced accidental toggling.

Premium materials ensure durability and consistent performance:

• Housing base: PPA (polyphthalamide) for superior thermal stability, chemical resistance, and rigidity under stress.
• Top housing: PC (polycarbonate) for toughness, clarity, and a smooth, professional finish.
• Terminals: Brass substrate with silver (Ag) plating to minimize contact resistance, prevent corrosion, and support reliable operation over tens of thousands of cycles.
• Actuator: PA66 (nylon 66) in a precise 2.8mm × 2.8mm square form factor, offering an ergonomic target for finger or tool operation in tight spaces.

Ideal for space-constrained, multi-signal environments, this switch finds strong use in:

• Consumer electronics — Remote controls, small handheld devices, portable audio players, or accessory buttons needing multi-channel selection or mode switching.
• Automotive/vehicle electronics — Low-current control switches in dashboards, infotainment interfaces, or accessory modules for non-critical functions.
• Industrial/test equipment — Mode selection, reset, trigger, or polarity-reversal buttons on meters, testers, analyzers, or control modules where handling multiple lines reliably is essential.
