Frequently Asked Questions

Q: What does SPDT mean on a micro limit switch?

A: SPDT stands for Single Pole Double Throw. It means the switch has one common terminal and two output terminals — one Normally Open (NO) and one Normally Closed (NC). This gives you flexible wiring options, allowing the switch to either complete or break a circuit when actuated. The Form C configuration in these micro limit switches makes them highly versatile for a variety of on/off control applications.

Q: What is the rated voltage and current for these micro limit switches?

A: These micro limit switches are rated for AC 250V and 5A, making them suitable for a wide range of home appliance and electronics projects. They also comply with EU LVD standards for low-voltage applications (below 50Vac or 75Vdc).

Q: Are these switches self-resetting, and how do they work?

A: Yes, these switches feature a self-resetting snap-action mechanism. When the actuator is pressed and then released, the switch automatically returns to its original position. This snap-action design ensures quick, positive switching with minimal operating force required (400 ± 50 gf).

Q: Which pack size should I choose?

A: If you're working on a small project or want to test compatibility, the 10-piece pack is ideal. The 50-piece pack suits medium-scale projects, while the 100-piece pack offers the best value for larger builds, production runs, or keeping spares on hand for future repairs and prototyping.
