Abstract
Abstract An electric switch comprises an insulating housing containing a movable contact operably connected to a finger operated pivotable actuator. The movable contact is formed as a resilient arcuate metal strip mounted at one end to the actuator such that the convex surface of the arcuate strip faces away from the actuator. A contact surface is formed on the convex surface of the arcuate strip adjacent the free end of the arcuate strip. The actuator is movable under finger pressure to two pivoted positions, one in which the movable contact surface disengages a stationary contact mounted in the bottom of the housing and one in which it engages the stationary contact.

Claim 1
Independent Claim
234 words
An electric switch comprising a housing of insulating material, a movable contact mounted in the housing and being formed as a resilient arcuate metal strip having a contact surface formed on the convex surface of the arcuate strip adjacent a free end of the arcuate strip for contacting at least one stationary contact, and an actuator to which the arcuate strip is directly connected at its other end with the convex surface of the arcuate strip facing away from the actuator, the actuator being pivotably mounted in the housing and being movable by finger pressure between a first pivoted position in which the contact surface is in a position corresponding to disengagement with the stationary contact and a second pivoted position in which the contact surface is in a position corresponding to engagement with the stationary contact, said housing having two shoulders engageable with respective abutment surfaces on the actuator to define the first pivoted position and the second pivoted position of the actuator, said housing further having two similar guide members spaced one on each side of the path of movement of the arcuate strip, each guide member having a cam surface engageable with a respective portion on the arcuate strip, the guide members serving to cam the free end portion of the arcuate strip upwardly from the bottom of the housing while the actuator is between the first and second pivoted positions.
