Product Information

Full details

This APEM 600 Series toggle switch, model 637H/2, is designed for robust control applications requiring precise switching, particularly for stop/start functions on power assemblies. It offers a reliable SPDT (Single Pole Double Throw) configuration with momentary On-Off-On functionality and durable solder lug terminals for secure connections. A key benefit is its panel-mount design and metal lever for straightforward integration and tactile feedback, though users should note its electrical life is rated at 10,000 cycles, which may require consideration for extremely high-usage scenarios.

FAQs

What does SPDT (On)-Off-(On) mean?

SPDT stands for Single Pole Double Throw. It means the switch has one input terminal and two output terminals. The (On)-Off-(On) configuration indicates that the two ON positions are momentary, meaning they only remain active while the lever is held in that position and return to the OFF center position when released. The center position is OFF.

What is the electrical life of this switch?

The electrical life of the APEM 637H/2 toggle switch is rated for 10,000 cycles under normal operating conditions.

Can this switch be used for AC and DC circuits?

Yes, this switch is rated for 250V AC and can also be used in DC circuits, provided the voltage and current do not exceed its specifications.

What type of terminals does this switch have?

This switch features solder lug terminals, which are designed for direct soldering of wires.

Is this switch suitable for outdoor use?

While built for robust industrial applications, specific environmental sealing (like IP ratings) is not detailed. It is best suited for protected control panels or indoor environments unless additional protective measures are taken.

What is the main application for this type of switch?

This type of switch is often used for stop/start functions on power assemblies, jogging controls, or any application requiring precise, momentary control over different functions.

Does the metal lever offer any advantage over plastic?

The metal lever provides enhanced durability, a more robust feel, and better resistance to wear and tear in demanding environments compared to plastic levers.

Troubleshooting

Switch does not function in one or more positions

Verify solder connections are secure and have not detached. Check for any physical obstruction preventing the lever from fully engaging the momentary action. Ensure the switch is correctly wired according to the circuit diagram.

Intermittent connection or flickering

Inspect solder joints for signs of stress or cold solder. Clean terminals if corrosion is present. Ensure the switch is properly seated and secured to the panel to prevent vibration-induced connection issues.

Switch feels loose or wobbly

Tighten the mounting nut securing the switch to the panel. Ensure a washer is used if required for proper seating.

Pros and Cons

Pros

  • Durable metal lever for reliable actuation.
  • Clear (On)-Off-(On) momentary functionality for precise control.
  • Panel mount design simplifies integration into existing systems.
  • Solder lug terminals ensure secure and straightforward wiring.
  • UL and CSA approvals indicate adherence to safety standards.

Cons

  • Electrical life rated at 10,000 cycles, which might be limiting for extremely high-frequency switching.
  • Momentary functionality means the switch returns to the OFF position when released, requiring sustained pressure for the ON states.
  • Only single pole, which may not be sufficient for complex multi-circuit switching.
  • Tab terminals are for solder connection, not suitable for push-on or screw terminal connections.

Setup, Compatibility & Care

Setup:

  1. Identify the mounting hole on your panel, typically designed for standard-sized toggle switches.
  2. Insert the threaded bushing of the switch through the panel hole.
  3. Secure the switch from the other side using an appropriate nut and washer (often supplied with the switch or panel). Ensure it is tightened firmly but do not overtighten.
  4. For electrical connections, prepare your wires and carefully solder them to the appropriate solder lug terminals according to your circuit diagram.

Compatibility:

  • This switch is designed for panel mounting. Ensure your panel material can accommodate a standard switch cutout.
  • The solder lug terminals are compatible with standard wire gauges suitable for 10A current and 250V AC voltage.
  • It is intended for DC or AC circuits within its specified voltage and current ratings.

Care:

  • Keep the switch clean and free from dust and debris. Use a dry or slightly damp cloth for cleaning; avoid solvents or abrasive materials.
  • Ensure connections remain clean and free from corrosion.
  • Periodically check the tightness of the mounting nut to ensure the switch remains secure.
