The PBS-33B is a compact waterproof momentary push button switch designed for 12mm panel mounting. It uses a self-resetting, non-locking action with 2-pin normally-open contacts, making it ideal for Arduino projects, appliance repairs, DIY electronics, toys, control panels, and low-voltage switching applications.
- 12mm panel mount push button switch
- Momentary self-reset operation
- 2-pin normally-open contact design
- Water-resistant mini plastic body
- Available in Black, Yellow, Blue, Green, Red and White
Momentary Operation
This switch is OFF by default and turns ON only while pressed. When released, it automatically returns to the OFF position. This makes it suitable for reset buttons, start buttons, signal inputs, trigger switches, and microcontroller input projects.
Please note: This is a momentary non-latching switch. It does not stay ON after being released.

Common Questions
Is this switch momentary or latching?
It is momentary. The switch turns ON while pressed and returns to OFF when released.
Is it normally open or normally closed?
This is a normally-open switch. The circuit is open by default and closes only while the button is pressed.
What size mounting hole does it need?
It is designed for a 12mm panel mounting hole.
Can I use it with Arduino?
Yes. It works well as a simple digital input button for Arduino, ESP32, Raspberry Pi Pico, and other microcontroller boards.
Can it switch mains voltage?
The switch has an AC rating, but for safety we recommend using it for low-voltage signal/control applications unless installed by a suitably qualified person.
Please note: Always confirm your wiring, voltage, and current requirements before installation.
