Abstract: A field configurable contactor is disclosed. The contactor preferably includes a plurality of spaces adapted to receive any number, up to its limit, of contact modules. Each contact module preferably includes a pair of contacts and a spring biased cam follower which opens and closes the contact pair when a cam profile of the contactor moves according to energization or de-energization of the contactor. The contact module can be either “normally open” or “normally closed” depending on its initial placement onto the contactor relative to the cam profile. A latch assembly in the contactor may hold the contactor mechanically during de-energization.

Abstract: An electromagnetic contactor that provides accurate contactor status indication regardless of the contact position. The primary contacts are secured within reversible contact modules. A contact carrier first end provides accurate local contact position indication. Auxiliary contacts toggled by the operator provide accurate control system status indication. The operator includes a stem with two sets of abutments that cooperatively engage the contact carrier. A catch located at the contact carrier second end and an abutment lip attach if the moveable contacts are welded shut. The operator status is prevented from changing thus insuring the accuracy of the contact position feedback. The contact modules can be installed in the electromagnetic contactor without the use of tools.

Abstract: A terminal apparatus for connecting an electrical conductor to electric equipment. A terminal is electrically coupled to the electric equipment and has a hole formed therethrough. A first securing member has a head and a shaft passing through the hole formed in the terminal. A first conductor receiving area is defined between the head and a first side of the terminal. A second securing member selectively engages the shaft on a side of the terminal opposite the head of the first securing member. A second conductor receiving area is defined between the second securing member and a second side of the terminal. A holder is coupled to the terminal and disposed on a side of the terminal corresponding to the second securing member. The holder retains the second securing member at a position in which the second securing member can be engaged with an end of the shaft when the shaft is inserted through the hole formed in the terminal.

Abstract: An electric switch having fixed contacts and rotary movable contacts in pairs. The movable contact have a central portion coupled to a rotary member and end portions adapted to contact the fixed contacts. The end portions extend from the central portion at an angle. The movable contact pairs lie in substantially the same plane.
