These versatile micro limit switches feature a compact 3-pin design perfect for PCB mounting applications. Each switch in this 20-pack comes with SPDT (Single Pole Double Throw) functionality, offering both normally open (NO) and normally closed (NC) circuit options. The durable snap-action mechanism provides crisp, reliable switching with every activation. Equipped with a roller lever actuator, these switches are ideal for precise position detection and control applications. Rated for 1A at 125V AC, they're suitable for various low-current control circuits in automation, security systems, and industrial equipment. The space-saving design and PCB terminal configuration make installation straightforward, while the robust construction ensures consistent performance through repeated use. These switches excel in applications requiring precise mechanical sensing, position detection, or end-of-travel indication. The roller lever design allows for smooth actuation from multiple angles, making them particularly effective in confined spaces where traditional switches might be impractical.
