switch function are identical the switch can function with various led or incandescent hand held flashlights of the tail cap variety and is designed to remain in off position until external forces are applied perpendicular to outer switch body or by twisting outer switch body in either direction the lobes or scallops 31 and 32 essentially create positive and negative portions of the switch bodies while in direct contact along a flat plane are insulted on that plane and while centered maintain uncommon polarities these flat insulated planes are designed to carry high strike loads perpendicular to insulated planes the switch bodies being cylindrical have an axis and while centered maintain uncommon polarities off position to complete a circuit forces of as little as 0 6 kg applied perpendicular to axis of cylindrical switch bodies will displace them from common axis though in some applications lower forces may be preferable and in other applications greater actuating forces may be more preferable the movement along the flat insulated plane will allow contact at un insulted internal peripheries on position when displacing force is removed from switch body the switch bodies will return to common axis and disconnect circuit to complete the circuit force may be applied at any point radial perpendicular to outer switch body in one embodiment when installed to the back of a flashlight pressure to the outer switch body by the thumb or while griped in one hand and forcing the side of the outer switch body in the palm of the hand with the fingers of the same hand will close circuit creating on position until side pressure is released at which point switch will return to off position.
