Product Information

Full details

This guide is for engineers, technicians, and hobbyists needing a reliable, high-current SPST toggle switch. Its key benefit is robust performance in demanding environments, suitable for industrial controls or power applications. A caveat is its specific maintained On-On functionality, which may require circuit design consideration. The APEM 600 Series toggle switch offers a durable solution for panel mounting, featuring a metal lever, silver nickel alloy contacts, and a significant electrical life.

FAQs

What does SPST On-On mean?

SPST stands for Single Pole, Single Throw. 'On-On' indicates that the switch has two stable (maintained) positions, and in each position, it connects a single pole (circuit) to one of two throws (outputs or states). It does not have a neutral or off position.

What is the electrical life of this switch?

The APEM 636H/2 toggle switch is rated for an electrical life of 10,000 cycles under normal operating conditions.

Can this switch be used in high-vibration environments?

While built for durability, for extremely high-vibration applications, ensuring a secure panel mount and considering additional locking mechanisms might be advisable. The maintained contact design helps prevent accidental switching.

What is the contact resistance?

The contact resistance for this switch is a low 0.01Ω, ensuring efficient current transfer with minimal power loss.

What is the operating temperature range?

The switch can operate reliably within a temperature range of -20°C to +55°C.

How do I connect wires to the switch?

This switch features solder lug terminals. Wires should be stripped and soldered securely to these lugs for a reliable electrical connection.

Is this switch suitable for AC or DC circuits?

Yes, it is suitable for both AC and DC circuits, provided the voltage and current do not exceed its rating of 250V and 15A respectively.

Troubleshooting

Switch does not change circuit state

Verify wiring connections to the correct terminals. Ensure the actuator is moving fully between the On-On positions. Check for physical obstructions preventing movement. Test continuity across the contacts in each position using a multimeter.

Intermittent connection or poor performance

Inspect solder connections for cold joints or damage. Ensure contacts are clean; if accessible and necessary, use an appropriate contact cleaner. Verify the switch is not overloaded beyond its 15A rating.

Switch feels loose after mounting

Tighten the mounting nut securely. Check if the panel thickness is within the specified range for the 12mm mounting bush.

Pros and Cons

Pros

  • High current rating (15A) suitable for power applications.
  • Durable construction with metal actuator and robust case.
  • Maintained On-On switching offers stable circuit control.
  • Wide operating temperature range for various environments.
  • Reliable silver nickel alloy contacts.

Cons

  • SPST configuration limits it to simple on/off or circuit switching, not complex multi-circuit control.
  • Maintained On-On functionality means it doesn't return to a neutral position.
  • Requires panel cutout and mounting hardware for installation.
  • Solder lug terminals may require specific tools and techniques for connection.

Setup, Compatibility & Care

Setup:

  1. Panel Preparation: Drill a 12mm diameter hole in the mounting panel.
  2. Installation: Insert the switch body through the hole. Secure the switch using the provided nut and washer (if applicable).
  3. Wiring: Connect wires to the solder lug terminals. Ensure proper soldering techniques for a secure and reliable connection.

Compatibility:

  • Panel Thickness: Designed for panels up to a certain thickness, typically specified by the mounting bush size (12mm).
  • Voltage/Current: Suitable for DC and AC circuits within its 250V, 15A rating. Always ensure compatibility with the specific application's electrical requirements.

Care:

  • Cleaning: Use a dry or slightly damp cloth to clean the actuator and surrounding panel. Avoid harsh solvents or abrasive cleaners.
  • Environment: While rated for a range of temperatures, prolonged exposure to extreme conditions or corrosive environments can impact longevity. Ensure the switch is protected from excessive moisture and dust.
  • Maintenance: Periodically check solder connections for integrity. The electrical life is rated at 10,000 cycles, after which performance should be monitored.
