It's equally useful for home automation DIY builds, low-power sensor nodes, and any project where a latching power switch is needed.\u003c\/p\u003e\n\n\u003cp\u003eFor more information on electronic component safety standards, visit the U.S. Consumer Product Safety Commission (CPSC).\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eQ: What does \"bistable\" mean for this switch module?\u003c\/h4\u003e\n\u003cp\u003eA: A bistable switch module has two stable states — ON and OFF. Once triggered by a single key press, it latches in that state and holds it without requiring any continuous signal or power. This makes it ideal for battery-powered and low-power electronics applications.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What voltage and current does this bistable switch module support?\u003c\/h4\u003e\n\u003cp\u003eA: This module operates on DC 2–5V, making it compatible with most microcontrollers, Arduino boards, and 3.3V\/5V logic systems. It supports a continuous load of up to 2A, suitable for driving small motors, LEDs, relays, or other low-power loads.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How small is this switch module, and will it fit in my project enclosure?\u003c\/h4\u003e\n\u003cp\u003eA: The module measures just 1.6 × 1.5 × 0.3 cm (approximately 0.62 × 0.59 × 0.11 inches), making it one of the most compact bistable switch solutions available. Its slim profile fits easily into tight enclosures, custom PCB layouts, and miniature DIY builds.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How many modules come in the pack?\u003c\/h4\u003e\n\u003cp\u003eA: This product is available in packs of 1 or 2 modules.
