This APEM toggle switch is designed for panel mounting and features an On-Off, SPST configuration ...This APEM toggle switch is designed for panel mounting and features an On-Off, SPST configuration with tab terminals. It has a contact current rating of 10 A @ 24 V dc. The actuator is made of Polyamide and has a length of 13.5mm. The contact material is Silver Nickel Alloy, with a contact resistance of 0.01Ω. The operating temperature range is from -20°C to +55°C.
This APEM toggle switch is ideal for panel-mounted applications requiring a reliable On-Off control. Its key benefit is a robust 10A contact current rating in a compact SPST configuration, suitable for various DC circuits. A minor caveat is its specific operating temperature range, which should be considered for extreme environments. Key features include durable Polyamide actuator, Silver Nickel Alloy contacts for low resistance, and convenient tab terminals for easy connection.

FAQs
What does SPST mean?
SPST stands for Single Pole, Single Throw. It means the switch has one input circuit that can be connected to or disconnected from one output circuit, providing simple On-Off functionality.
Can this switch be used for AC power?
While some APEM toggle switches are rated for AC, this specific model's detailed description emphasizes its 10A @ 24Vdc rating. It is best suited for DC applications. Using it for AC may require consulting the full datasheet or specific application suitability.
What size hole is needed for mounting?
This switch is designed for a 12mm mounting bush, so a 12mm diameter hole is typically required.
What is the contact resistance?
The contact resistance for this switch is 0.01Ω (10mΩ), indicating good conductivity and minimal power loss.
What material are the contacts made of?
The contacts are made of a Silver Nickel Alloy, known for its durability and low resistance.
What is the actuator material?
The actuator (lever) is made of Polyamide.
What is the warranty period for this switch?
Please refer to the manufacturer's warranty information or the retailer's policy for specific warranty details, as this information is not provided in the product description.
Troubleshooting
Switch not making connection (no power flow)
Ensure the switch is in the 'On' position. Verify wiring connections to both the switch terminals and the power source/load. Check if the current draw exceeds the 10A rating, which could have tripped internal protection (if any) or damaged contacts.
Switch feels loose after mounting
Tighten the mounting nut securely. Ensure the panel cutout is the correct size for the 12mm bush.
Intermittent connection or high resistance
Check for any debris or corrosion on the tab terminals. Clean terminals gently if necessary. Ensure the operating temperature is within the specified range.
Pros and Cons
Pros
Reliable On-Off functionality for simple circuit control.
High current rating (10A @ 24Vdc) for demanding applications.
Easy installation and connection with tab terminals.
Durable construction with Polyamide actuator and Silver Nickel Alloy contacts.
Compact design suitable for panel mounting.
Cons
Limited to SPST (On-Off) functionality.
Operating temperature range is restricted to -20°C to +55°C.
Not suitable for AC applications without appropriate circuitry.
Requires panel cutout for mounting, which might not be universal.
Setup, Compatibility & Care
Setup:
Panel Preparation: Ensure your panel has a suitable cutout for the 12mm mounting bush.
Mounting: Insert the switch into the panel cutout and secure it using the provided nut (if applicable).
Wiring: Connect your load and power source to the tab terminals. Ensure the power is disconnected before wiring.
Compatibility:
Voltage: Primarily designed for DC applications up to 24V. While the model `631NH/2` mentions 250V, the detailed description specifies 10A @ 24Vdc, indicating DC is the primary intended use. Always verify specific voltage compatibility for your application.
Current: Suitable for circuits drawing up to 10A.
Mounting: Requires a 12mm mounting hole.
Care:
Cleaning: Wipe the switch and actuator with a dry or slightly damp cloth. Avoid using abrasive cleaners or solvents that could damage the materials.
Environment: Operate within the specified temperature range (-20°C to +55°C) and avoid excessive moisture or corrosive substances.
