Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
177 words
A pendulum switch comprising: means for mounting the switch to a support, said mounting means comprising means by which the three dimensional position of a switch housing carried by the mounting means may be adjusted; normally spaced first and second electrically conductive means respectively adapted to be connected to a source of electrical energy and to a circuit, one of said conductive means comprising a pivotal pendulum rod and the other an eyelet; and meAns for adjusting the sensitivity of the switch comprising anchor means in the form of a body of material having a tapped central bore and carrying said eyelet and means for displacing the anchor means and eyelet in the form of a threaded shank threadedly joined to the anchor means at said bore and including a knob by which the shank is rotated to elevate or lower the anchor means and eyelet as a unit generally in respect to the axis of the pendulum rod so as to change the distance of the pivot point of the pendulum rod relative to the eyelet.
Claim 2
Dependent Claim
177 words
