Abstract
Abstract Switch-actuating means employing an eccentric cam which is supported above a surface for rotational sliding engagement with the operating lever arm of a switch. The switch is carried above the surface on a mounting bracket which includes means for adjusting the position of the switch lever arm in the path of rotation of the cam, whereby the electrical condition of the switch corresponds to the desired rotational condition of the shaft on which the cam is carried for accurately controlling the prime mover of a valve so that the prime mover is deenergized upon operation of the valve thereby to an open or a closed condition.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
230 words
An electromechanical control apparatus comprising: mechanical control means including a movable control member which is positionable to first and second positions; electrical switching means having first and second electrical conditions corresponding to the first and second positions, respectively, of said movable member, including a movable switching member; and means for mounting said switching means with said movable switching member adjacent said movable control member for operable engagement thereby, said mounting means including a mounting surface, means for movably mounting said switching means including a base pivotally connected to said mounting surface to provide movement of said switching means along an arcuate path to adjust said movable switching member relative to said movable control member so that the operation of said switching means to said first and second electrical conditions may be varied relative to the first and second positions of said movable member, and means for selectively positioning said base about its pivot relative to said movable control member including wall means in said base defining an aperture through said base, and selective positioning means including a positionable cam pivotally carried on said mounting surface and disposed in said aperture, said cam being in constant abutment with said wall means and said wall means being in confining and surrounding relation to said cam to selectively and positively position said base and said electrical switching means relative to said control member.
