Frequently Asked Questions
Q: Are these push button switches compatible with Arduino microcontrollers?
A: Yes! The PBS-33B 12mm momentary push button switches are fully compatible with Arduino, Raspberry Pi, and most other microcontroller platforms. Their standard pin configuration makes wiring straightforward for both beginners and experienced makers.
Q: What does "momentary" mean for these switches?
A: A momentary switch only completes the circuit while the button is actively being pressed. Once released, the circuit opens again. This makes them ideal for triggers, resets, doorbells, or any application where you need a temporary signal rather than a latching ON/OFF state.
Q: How waterproof are the PBS-33B switches?
A: These switches feature a waterproof design that protects the internal contacts from moisture and light splashing, making them suitable for outdoor enclosures, wet environments, or applications where occasional exposure to water is possible. They are not designed for full submersion.
Q: What panel hole size is required to mount a 12mm push button switch?
A: These 12mm round push button switches require a 12mm diameter panel cutout for mounting. They are designed to snap or thread into standard 12mm holes in metal or plastic panels.
