niter's Usage Examples:

While some larger models feature pilot lights, most portable models use a quartz igniter to ignite the propane as it exits the element.

When the spark igniter is made conductive, the storage capacitor discharges the remainder of its accumulated energy.

The pyro-electric characters of quartz are closely connected with its peculiar type of symmetry and especially with the three uniterminal dyad axes.

The new igniter - an Aerotech motor igniter from a larger motor - only just fit in the slot, and looked very chunky.

Crystals of this class possess neither planes nor centre of symmetry, but only axes of symmetry: perpendicular to the principal triad axis there are three uniterminal dyad axes of symmetry.
