Product Information

Full details

This APEM 631H/2 toggle switch is designed for professionals needing a reliable single-pole, single-throw (SPST) On-Off switch for panel mounting. Its key benefit is robust performance in demanding applications with a 15A/250V rating. A potential caveat for some users might be its solder lug connection, which requires soldering expertise for installation. This guide will cover its features, applications, and essential usage information.

FAQs

What does SPST On-Off maintained mean?

SPST stands for Single Pole, Single Throw. 'On-Off maintained' means the switch has two stable positions: On and Off. It stays in the position you set it to until you manually flip it to the other position. It does not return to a default position on its own.

What size hole is needed to mount this switch?

This switch requires a 12mm mounting bush cutout in the panel.

Can this switch be used for AC and DC circuits?

Yes, it can be used for both AC and DC circuits, provided the voltage and current do not exceed its 250V and 15A rating.

How do I connect wires to the switch?

The switch features solder lug terminals. You will need to tin your wires and solder them securely to these lugs.

What is the electrical life of this switch?

The electrical life is rated for 10,000 cycles, meaning it is designed to withstand 10,000 operations under its specified load conditions.

Does this switch have momentary positions?

No, this specific model (631H/2) is an On-Off maintained switch and does not feature momentary positions.

What materials are the contacts made of?

The contacts are made of a Silver/Nickel Alloy, which provides good conductivity and durability.

Troubleshooting

Switch not making connection (no power flow)

Verify that the solder connections are secure and have not become loose. Ensure the switch is in the 'On' position. Check the integrity of the wires connected to the lugs.

Switch feels loose or wobbly

Tighten the mounting nut on the panel. Ensure the panel cutout is the correct size for the 12mm mounting bush.

Switch lever is stiff or difficult to move

Ensure there is no obstruction around the lever. Check that the switch is not over-tightened on the panel. If the issue persists, the internal mechanism may be damaged.

Overheating during operation

Ensure the load current does not exceed the 15A rating. Check that the connections are clean and well-soldered to minimize resistance. Overheating may indicate a faulty switch or an overloaded circuit.

Pros and Cons

Pros

  • High current and voltage rating (15A, 250V) suitable for demanding applications.
  • Durable construction with metal lever and robust case materials.
  • Maintained function provides reliable and predictable circuit control.
  • UL and CSA approvals offer assurance of safety and quality.
  • Simple SPST design is easy to understand and implement.

Cons

  • Solder lug terminals require soldering skills for installation.
  • Momentary positions are not supported in this On-Off maintained model.
  • Limited to single-pole switching, may not be suitable for complex multi-circuit control.
  • Panel mounting requires appropriate cutout and securing mechanism.

Setup, Compatibility & Care

Setup:

  1. Panel Preparation: Ensure you have a suitable panel with a 12mm mounting bush cutout.
  2. Mounting: Insert the switch through the cutout and secure it using the provided nut and washer.
  3. Wiring: Connect wires to the solder lugs. This requires appropriate soldering equipment and techniques to ensure a secure, low-resistance connection.
  4. Circuit Connection: Connect the switch to your electrical circuit according to its SPST On-Off function.

Compatibility:

  • This switch is designed for panel mounting.
  • It is compatible with DC and AC circuits within its 250V/15A rating.
  • The solder lug terminals are designed for solid or stranded wires that can be soldered.

Care:

  • Keep the switch clean and free from excessive dust or moisture.
  • Avoid applying excessive force to the lever, which could damage the internal mechanism.
  • Periodically check solder connections for integrity, especially in high-vibration environments.
