Spring return

Order code: M470
Ordering data: Return variation
Available for: All cam-switches of size S0 - S2 depending on the variation

Spring return for angular displacement up to 30° can be accomplished by using the latching mechanism. If a large number of contacts must be opened simultaneously or a total angular displacement is larger then 30° over which the spring return is operational, the switch must use one of the spring return devices.
