A stopped hole drilled in the front center portion of the hammer mass facing the tumbler acts as a receiver for the rod, and as an anvil for the punch action. The tumbler provides the automation. When reset, a provision is made such that the tumbler rod is cocked slightly, so that its resting position is skewed and the tip contacts the hammer ...
An electrical component mounted in this manner is referred to as a surface-mount device (SMD). In industry, this approach has largely replaced through-hole technology construction method of fitting components, in large part because SMT allows for increased manufacturing automation which reduces cost and improves quality.
