Latest Patents
One of Tsai's latest patents is for an electric switch having an improved lever operator arrangement. This invention features a lever-operated rotary reversing switch where the lever is snap-fit attached to the switch housing. A portion of the lever is inserted under an overhang on the housing to maintain that portion against the exterior surface. A detent is provided between the overhang and the end of the lever to direct forces longitudinally in the plane of the lever. Additionally, a rotor plate located exteriorly of the housing is connected to the rotor by an axial shaft, with an eccentric received in a slot in the lever to provide a driving coupling between the lever and the internal contact mechanism.
Another notable patent is for an electric switch with a dynamic brake contact shared for making and breaking circuits. This double pole single throw electric switch has normally closed contacts of one pole connected in a dynamic braking circuit with a motor load. The normally open contacts connect the motor to a power source. A partial movable contact is conductively connected to the movable contacts of the normally open contacts, providing a parallel path through the switch for making and breaking the circuit to the power source.
