A single pole single throw switch (SPST) is used to open or close a contact to a single wire. It can be used as an on/off switch for an appliance or for a light bulb.
An SPST switch can break the connection or hold the connection depending on which switch your using.

It stands for Single Pole Single Throw
SPST stands for Single-Pole, Single-Throw, and is a designation for the switch contact arrangement that has just two terminals. As the switch is thrown, these two terminals will be either open or closed depending on the position of the handle.
SPST stands for Single Pole Single Throw, indicating a type of switch that controls a single circuit. It has two positions: open (off) and closed (on), allowing current to flow or stopping it. This simple switch design is commonly used in basic on/off applications. In an electrical diagram, an SPST switch is represented by a specific symbol denoting its functionality.
To control a lamp independently using a Single Pole Single Throw (SPST) switch, connect one terminal of the switch to the live wire from the power source and the other terminal to the lamp's live input. The neutral wire from the power source should be directly connected to the lamp's neutral input. When the SPST switch is in the "on" position, it completes the circuit, allowing current to flow to the lamp and turn it on; when in the "off" position, it breaks the circuit, turning the lamp off.
No it is not hard to tell them apart. A Single Pole Single Throw switch will go directly from the on position to the off position breaking the circuit. This is the type of switch that is used in homes for lighting control. A Single Pole Double Throw switch will usually have a stop indent which is the off position mid way through the throw. This is the switch that is used for a transfer switch when using a stand by generator in the system. The full up (on) position is usually connected to utility power. The full down (on) position is usually connected to the stand by generator.
You need a normally closed SPST momentary switch. There are several different kinds available at Radio Shack.
There are two primary ways to debounce a switch. In an SPST configuration, you scan the contact fast enough to see the bounces and you decide what constitutes a single press, based on your design criteria. This can become unreliable as the switch wears. In the SPDT configuration, you use an SR flip-flop and that debounces the switch. That is more reliable, but more complex. You decide.
In electronics, SPDT refers to a particular type of switch; a "Single Pole Double Throw" style. Other flavors I think you may recognize now are SPST, DPDT, and TPDT. It breaks down like this; the "Pole" count (single, double, triple, etc.) refers to the number of switch contact sets that are connected to the switch lever. The "Throw" count refers to the number of positions the switch lever is designed to be set to. Light switches in your house are SPST switches.
