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.

A SPST switch is the type used for turning the lights on and off in your home lighting systems. It is just basically just an on - off switch.

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.
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.
Without an indication of what you want the indicator light to do, this question can not be answered.
This is the typical light switch in your home that controls a single light from a single location. Sometimes you might see it described as SPST or single pole single throw.
