Abstract
A switch lock for an electrical switching device, e.g. a circuit breaker, motor circuit breaker, or isolating switch, which is an improved switch lock, that can be made with fewer parts and at lower cost. Furthermore, an electrical switching device can contain this switch lock. Due to an appropriate arrangement of the spring coupling points and an appropriate spring dimensioning, as well as an appropriate geometric design of the contact piece holder, this switch lock can do without separate lock and contact pressure springs, insofar as their functions are combined in one spring.
