Push Switch

For low-voltage DC electronics, these miniature PCB-mount push switches are the industry standard for reliability and space-saving design. Commonly referred to as "Self-Lock" or "Momentary" tactile switches, they are engineered for low-current signals in everything from consumer electronics to industrial bread boarding.

Product Overview

These sub-miniature switches are designed for Through-Hole Technology (THT) mounting. They feature a high-precision internal spring mechanism that ensures a definitive tactile click, providing the user with clear physical feedback. Available in three standardized footprints, they offer a range of travel distances and mechanical strengths to fit your specific PCB layout.

Available Form Factors

5.8 x 5.8mm: The "Ultra-Compact" choice. Best for high-density boards, wearables, or handheld remote controls where every millimeter counts.
7.0 x 7.0mm: The "Industry Standard." This is the most versatile size, offering a perfect balance between a small footprint and ease of manual soldering.
8.5 x 8.5mm: The "Heavy-Duty" variant. Featuring a slightly larger plunger surface and more robust housing, it's ideal for control panels where users might apply more forceful pressure.

Mechanical Configurations

1. Momentary (Non-Locking)

Action: The circuit stays closed only as long as the button is depressed.
Mechanism: Returns to the "UP" position immediately upon release.
Application: Reset buttons, signal triggers, or micro controller interrupts.

2. Latching (Self-Locking)

Action: The first press locks the plunger down and completes the circuit; the second press releases the lock and breaks the circuit.
Mechanism: Features a "push-on, push-off" mechanical heart track.
Application: Main power toggles for battery-operated devices, LED mode selection.

Key Features

High-Quality Materials: Silver-plated contacts ensure low contact resistance and prevent oxidation over time.
Standardized Pin Pitch: Designed to fit standard $2.54\text{mm}$ (0.1") pitch prototyping boards and breadboards (with slight leg forming).
Tactile Feedback: A sharp, audible "click" confirms the switch has been successfully actuated.
Heat Resistant: Durable PBT/PA66 housing prevents melting during standard soldering procedures.
