Tact switches are commonly used in many consumer electronic devices. They have a small footprint and come in many sizes and gram forces.

Tact switch Applications:
1. Telecommunications
2. Consumer electronics
3. Audio/visual
4. Medical device
5. Testing/instrumentation
6. Computer peripherals

What is a tact switch in electronics? 
A tact switch is type of switch that is only on when the button is pressed. As soon as you release the button, the circuit is broken. Think of the keys on a keyboard.

Ceramic capacitors are constructed with materials such as titanium acid barium used as the dielectric. Internally, these capacitors are not constructed as a coil, so they can be used in high frequency applications. Typically, they are used in circuits which bypass high frequency signals to ground.

These capacitors have the shape of a disk. Their capacitance is comparatively small.

• The capacitor on the left is a 100pF capacitor with a diameter of about 3 mm.
• The capacitor on the right side is printed with 103, so 10 x 103pF becomes 0.01 µF. The diameter of the disk is about 6 mm.
• Ceramic capacitors have no polarity.
• Ceramic capacitors should not be used for analog circuits, because they can distort the signal.
