Abstract: A tilt switch includes an insulating housing with two first insert holes proximate to a bottom wall and aligned with each other and defining a first distance, and a second insert hole proximate to a top wall. Two first and one second electric contact members include first and second insert end portions press fitted within the first and second insert holes and extending into the housing, and first and second electric contact terminals extending outwardly of the housing. The second insert end portion is spaced apart from the first insert end portions with a second distance.

Abstract: A tilt switch includes an insulating switch body with top and bottom walls and an inner circumferential wall surrounding an upright central axis. An upright electric contact member is secured to the top wall, and extends along the central axis to form a first electric contact terminal outwardly of the bottom wall. An annular electric contact member engages the inner circumferential wall, and has an inner peripheral wall, and an annular rolling surface forming with the inner peripheral wall at the juncture thereof an annular edge. A second electric contact terminal is integrally formed with the annular electric contact member, and extends downwardly and outwardly of the bottom wall.
