An automatic turn-off switch responsive to displacement of a movable element placed on a seat which resides on the top of a chute located with an opening at the bottom immediately adjacent to a pivotal lever. A spring-loaded latch is normally biased in a contracted condition. An automatic release is cooperatively carried between the spring latch and the lever whereby displacement of the mechanical movable element causes the release to disconnect from the contracted latch, whereby the latch is released for forcible engagement with a conventional on/off switch in a circuit breaker box. When the circuit breaker switch is in the “on” position, the released latch engages the switch and causes the switch to move to its “off” position, terminating all electrical communication with the main power source.

An internal combustion engine includes at least one piston that compresses air in the lower cylinder chamber as it transitions from top dead center to bottom dead center during the power stroke. The air in the lower cylinder chamber is compressed between the downward-moving cylinder and a structure that substantially seals the lower chamber from the crankcase chamber so that compression takes place in a chamber smaller than the crankcase chamber.
