Switch controlling motor- and braking windings of hand tool, delays change-over from running to braking and vice versa, preventing excessive arcing at switch contacts, to prolong switch life and increase user safety

摘要

Additional switch contacts (S2, S3) also have a delay, retarding change over from braking to driving, and vice versa. The design is such that delay intervals for the switch contacts (S1, S2, S3) differ.
