ABSTRACT:
A universally tilted inclination switch includes: a housing having a conical recess recessed downwardly in the housing, an actuating ball gravitationally rested on a central portion of the conical recess of the housing, a pair of terminals electrically connected to two poles of a power source of an electrical circuit, and a conducting disk normally gravitationally riding on the pair of terminals for electrically contacting the pair of terminals for closing the electrical circuit, whereby upon tilting of the housing to move the actuating ball, the conducting disk will be upwardly biased to disconnect the pair of terminals to open the circuit, thereby providing an inclination switch universally tilted to any orientation about the vertical axis for a more sensitive actuation of the switch for opening or closing the electrical circuit.
