APEM Toggle Switch 656H/2 3PST On-On 250V 15A

3PST stands for Triple Pole Single Throw, meaning the switch has three independent sets of contacts. 'On-On' indicates that each set of contacts has two stable positions, connecting the circuit in one position and disconnecting it in the other, and it remains in the selected position.

The APEM 656H/2 toggle switch has an electrical life of 10,000 cycles under normal operating conditions.

This switch is primarily rated for AC circuits. Using it in DC circuits may lead to reduced performance or premature failure due to different arc characteristics. Consult the manufacturer's specifications for DC suitability.

This model features solder lug terminals for electrical connections, which require soldering wires directly to the terminals.

The switch is rated for a maximum of 250V AC and 15A.

No, this is a maintained switch. Both 'On' positions hold their state until manually changed. It does not have a spring-return or momentary function.

Verify power is supplied to the switch. Check all solder connections for continuity and ensure they are secure. Inspect the lever mechanism for any obstructions.

Immediately disconnect power. Ensure the load does not exceed the switch's 15A rating. Check that all connections are clean and tight. If arcing persists, the switch may be damaged and require replacement.

Inspect the switch mounting to ensure it is secured to the panel. Check for any foreign objects impeding the lever's movement.
