Abstract

Abstract The invention relates to a tease-proof electric switch in which the switch contacts cannot be partially opened or closed by manipulation of the mechanism. The switch employs a contactcarrying rocker which moves positively between open and closed positions of the switch under the influence of forces exerted thereon by an operating member. Movement of the rocker between open and closed positions of the switch is restrained by a releasable latch. Opening and closing of the switch contacts takes place upon release of the latch from engagement with the rocker as the result of forces exerted on the rocker by the operating member. Opening and closing of the switch contacts also takes place positively and quickly with arcing being held to a minimum.

Claim 6
Dependent Claim 232 words
In an electric switch, the combination which comprises: a. a hollow housing; b. said housing comprising a cover and a base; c. a curved rocker member of electrically conductive material rockably supported on said base for movement between an open and a closed position of the switch; d. a pivot member of conductive material extending upwardly from said base and electrically engaging with the rocker memBer at a point intermediate its ends; e. an operating member slidably mounted in said housing and engaging with the rocker member; f. said operating member being slidable lengthwise relative to the rocker member and exerting a downward force on opposite ends of the curved rocker member in said movement; g. a resilient contact arm of conductive material supported at one end of the base in opposing relation to a first end of the rocker member; h. an end of said resilient arm being yieldably urged toward engagement with said first end of the rocker member; and i. a resilient latch member releasably engaging with a second end of the rocker member; j. said latch member releasably engaging with the second end of the rocker member and restraining movement of the rocker member into and out of engagement with the resilient contact arm until a downward force is exerted by the operating member on a raised portion of the rocker on one side of the pivot member.
Claim 7
Dependent Claim 232 words
In an electric switch, the combination which comprises: a. a hollow housing; b. said housing comprising a cover and a base; c. a curved rocker member of electrically conductive material rockably supported on said base for movement between an open and a closed position of the switch; d. a pivot member of conductive material extending upwardly from said base and electrically engaging with the rocker memBer at a point intermediate its ends; e. an operating member slidably mounted in said housing and engaging with the rocker member; f. said operating member being slidable lengthwise relative to the rocker member and exerting a downward force on opposite ends of the curved rocker member in said movement; g. a resilient contact arm of conductive material supported at one end of the base in opposing relation to a first end of the rocker member; h. an end of said resilient arm being yieldably urged toward engagement with said first end of the rocker member; and i. a resilient latch member releasably engaging with a second end of the rocker member; j. said latch member releasably engaging with the second end of the rocker member and restraining movement of the rocker member into and out of engagement with the resilient contact arm until a downward force is exerted by the operating member on a raised portion of the rocker on one side of the pivot member.
