Abstract: A terminal cover for use on molded case circuit breakers. The terminal cover limits access to circuit breaker electrical terminals and uninsulated portions of electrical conductors entering the terminals. The terminal cover also provides selective access to the terminal binding screws.

Abstract: The objective of the invention is to provide a compact and complex electronic component incorporating a rotary encoder capable of exact adjustment and a push switch with a long life-cycle. In order to achieve the objective, the push switch is fixed on a rear wall or a lower surface of the electronic component such that an essential of the push switch, i.e., a dome-shaped member, can be made larger and has longer fatigue life. Moreover, the rotary encoder includes a rotatable member and a resilient member. The rotatable member has a gear-shaped flange and is rotatable circumferentially relative to a central shaft of the rotary encoder. When the rotary encoder rotates, the resilient member, relative to the central shaft, is stationary. The resilient member has a V-shaped portion retained by a surface of the gear-shaped flange of the rotatable member such that the rotary encoder can be exact adjusted.
