machine internal subassembly and the external
cover are configured so that the mechanism to be manually actuated
extends through the cover. In another configuration buttons are
mounted on an elastic diaphragm so that they protrude through a large
hole or separate holes in the cover. The reverse sides of the
buttons or the diaphragm itself can be used to actuate mechanisms
such as switches.
actuator usually consists of a push button, springs,
guides and other items, which is a complex assembly that is labor
intensive to assemble. The switch actuator disclosed herein consists
of a simple plastic injection-molded part which attaches to a machine
bezel via simple snaps molded integrally with the machine or system

typical bezel showing the switch actuator separated from the snaps.
Fig. 2 is sectional view across A-A of Fig. 1. Fig. 3 is a detail
view from Fig. 2 showing the switch actuator and switch in a
depressed position. In operation, the snaps act as pivots, allowing
the actuator to swing, thereby converting a rotary motion into a
