I replaced mine with 502B endcaps.

Remember to exercise proper laser safety and store your pointers in a safe place once you replace the key caps with button caps.

It is important to remember to exercise proper laser safety when using laser pointers, especially when replacing key caps with button caps. The use of laser pointers can be dangerous if not used responsibly, as the laser beam can cause eye damage or even blindness. It is essential to always follow the manufacturer's instructions and guidelines for safe use, including never pointing the laser at people or animals.
In addition to exercising proper laser safety, it is also important to store your laser pointers in a safe place when not in use. This will help prevent accidental exposure to the laser beam and reduce the risk of injury or damage. A locked cabinet or drawer, or a case specifically designed for laser pointers, would be a good option to ensure that the pointer is stored securely and out of reach of children or anyone else who should not have access to it.
In summary, exercising proper laser safety and properly storing your laser pointers are crucial steps to ensure the safe use of these devices and avoid injury or damage.

Positive earth or negative earth? I had the same issue with positive earth -- I just pop a five cent piece (same as a wheat penny) over the top and it pushes down on the pressure spring, resulting in circuit for positive earth. negative earth be more careful, many points of short circuit.
