Class Information
Number: 200/
Name: Electricity: circuit makers and breakers > Snap
Description: This group relates to circuit makers and breakers which are constructed to operate with a quick motion. They are limited to those switches in which the quick motion of the contacts is not dependent on the rate of movement of the operator. This is usually accomplished by a spring connection between the operator and the switch-contact, so that the initial movement of the operator puts the spring under tension and when the contact is released it is snapped by action of the spring.
