Product Description: Miniature Illuminated DPDT Push Button Switch ( Self Lock Illuminated Tact Switch)
This miniature illuminated push button switch—often referred to as an illuminated tact switch—combines compact mechanical precision with vibrant visual feedback. Designed for applications where space is limited but reliability is paramount, this component is an ideal choice for instrumentation, automotive controls, medical devices, and industrial keypads.

Electrical & Mechanical Specifications
The switch features a DPDT (Double Pole Double Throw) circuit configuration, allowing it to control two independent signals or change between two load paths simultaneously. It is rated for DC30V at 0.1A, making it suitable for low-voltage logic-level switching. The compact outline measures a mere 7.5mm x 8.5mm, fitting easily into dense PCB layouts. Regarding tactile feel, the switch offers a precise Lock Travel of 1.4mm and a Total Full Travel of 1.6mm, ensuring a crisp, confident actuation. With an Actuator Height of 10mm off the PCB, it provides adequate clearance for panel mounting. The LED lead spacing is 10.16mm, conforming to standard breadboard and PCB grid spacing.

Mounting & Assembly
The switch features a through-hole mounting configuration, with robust leads designed to be inserted into drilled PCB holes and soldered from the underside. This provides superior mechanical pull strength compared to SMD alternatives, making it highly resistant to vibration or rough handling during operation.

Functionality & Illumination
This switch is available in two primary operational modes: Latching (push-on, push-off) and Momentary (active only while pressed). A wide range of LED color options is offered, including single colors (Red, Yellow, Green, Blue, White) and dual-color combinations (Red/Yellow, Red/Green, Red/Blue), enabling custom status indication or aesthetic design.

Durability & Customization
Engineered for longevity, the switch boasts a mechanical lifecycle of 30,000 cycles. Two snap-on keycap options are available: Option 1 features a 10×10 mm square cap with a height of 10.65 mm, while Option 2 is a round cap (10 mm diameter, 9.4 mm height). Both caps provide enhanced tactile surface area and can be color-matched to the LED.

This through-hole illuminated DPDT push button switch delivers professional-grade switching and robust anchorage in a tiny, light-up package.
