2. Understanding the Basics: Types of Killswitches

Before diving into the installation, it’s crucial to understand the different types of killswitches available. The choice depends on your desired effect and guitar setup.

2.1 Momentary vs. Latching Switches

The primary distinction lies in how the switch behaves:

Momentary Switches: These only interrupt the signal while pressed or held. As soon as you release the switch, the signal returns. This is the most common type for killswitches, as it allows for rapid, controlled stuttering effects.
Latching Switches: These toggle between on and off states with each press. They stay in the selected position until pressed again. While less common for typical killswitch effects, they can be used for muting entire sections of a song.

2.2 Normally Open (NO) vs. Normally Closed (NC) Switches

This refers to the default state of the switch:

Normally Open (NO): The circuit is open (no signal) until the switch is activated, completing the circuit.
Normally Closed (NC): The circuit is closed (signal passing) until the switch is activated, opening the circuit and cutting the signal. Most killswitches use a normally closed configuration.

2.3 SPST vs. SPDT Switches

These terms refer to the number of poles and throws in the switch:

SPST (Single Pole Single Throw): The simplest type, with two terminals. It either connects or disconnects the circuit.
SPDT (Single Pole Double Throw): Has three terminals, allowing you to switch between two different circuits. While usable for a killswitch, it’s not typically necessary.

2.4 Choosing the Right Switch

For most killswitch applications, a momentary, normally closed (NC), SPST switch is ideal. This configuration provides the classic stuttering effect.
