Electric Squib Assembly

An electric squib assembly, also known as an electric igniter or electric detonator, is a device used to initiate or trigger an explosive or pyrotechnic material. It consists of an electrical circuit that, when activated, generates a high current or voltage pulse to ignite the explosive material.

The main components of an electric squib assembly include:

1. Initiator: This is the part of the assembly that contains the explosive material. It is designed to be sensitive to electrical current or voltage and initiate a rapid combustion or explosion when activated.

2. Bridge wire: The bridge wire is a thin, resistive wire that is heated by the electrical current passing through it. When the bridge wire reaches a certain temperature, it ignites the initiator, initiating the explosion or combustion process.

3. Firing circuit: The firing circuit is the electrical circuit that delivers the current or voltage pulse to the bridge wire. It typically consists of a power source, such as a battery or capacitor, and a switch or electronic control device to activate the circuit.

Electric squib assemblies are commonly used in various industries, including aerospace, defense, automotive, and entertainment. They are used for applications such as initiating airbag deployment in vehicles, activating pyrotechnic devices in fireworks or special effects, and triggering explosive charges in military or demolition operations.

It is important to note that the use and handling of electric squib assemblies should be done with utmost care and in accordance with safety guidelines and regulations, as they involve the use of explosive materials.
