A simple SMD slide switch. Perfect for when you need access to a setting or a power switch from the edge of a PCB buried deep within a project. Features: 4V - 300mA. 70mOhm resistance. 10,000 cycle life.
This 200 pulse per rotation rotary encoder outputs gray code which you can interpret using a microcontroller and find out which direction the shaft is turning and by how much. This allows you to add feedback to motor control systems. Encoders of this kind are often used in balancing robots and dead reckoning navigation but it could also be used as a very precise input knob.
This is a carbon fiber safety cover protects a toggle switch from accidentally being turned on.
This through-hole speaker is great for projects where you need something that sounds better than a piezo buzzer but don't have room for a full-blown speaker. This 30mm diameter speaker is encased in plastic and will handle about 100mW of power.
