What does sealed mean in a micro switch?

A sealed design protects the switch contacts and mechanism from dust, moisture, and contaminants, extending life and reliability in harsh industrial environments.

Can I use this switch at higher voltages or currents?

No. The A-20GQ-B is strictly rated 12V DC / 0.1A maximum. Exceeding these limits voids warranty and risks failure or safety hazards.

What is snap-action switching?

Snap-action means contacts move rapidly once actuation force is reached, providing decisive, bounce-free switching ideal for precise digital signals.

How many times can this switch cycle?

The A-20GQ-B is rated for approximately 1,000,000 mechanical cycles under normal operating conditions.

What temperature range is this switch rated for?

Operating range is -10 to 60°C. Outside this range, electrical characteristics and mechanical life may be compromised.

Is this suitable for outdoor installation?

The sealed design provides excellent contamination protection. For full outdoor use, ensure the enclosure and mounting meet required IP protection ratings.

What do the terminal codes mean?

The 'B' suffix indicates a specific terminal type (solder, quick-connect, or PCB). Verify with Omron datasheets for your exact configuration.
