Contact movement is blocked until spring is charged:
(under subclass 405) Subject matter including, a spring connection between the actuator and moveable contact, and an element which blocks the movement of the contact until the actuator has moved to stress the spring and moves the blocking element from its blocking position.
(1) Note. Included herein are devices wherein the blocking element is part of the actuator.
(2) Note. Normally one end of the spring is directly driven by the actuator and the other end of the spring directly drives the contacts. However, the switch may also include intermediate linkages between both the actuator and a spring driving element and the contacts.

411, for similar-type devices using a rotating contact.
