Modular Electrical Switch And Switching Assembly For Industrial Elevators

US Patent:
5508480, Apr 16, 1996
Filed:
Sep 24, 1993
Appl. No.:
8/126994
Inventors:
Ronald D. Quinlan - Pacific MO
Assignee:
JPB Enterprises, Inc. - St. Louis MO
International Classification:
H01H 118
H01H 926
US Classification:
200 16A
Abstract:
A modular electrical switch provides a wiping or shearing action upon closing and opening thereof. A contact carrier disposed within a housing linearly carries a movable contact into engagement with a stationary contact. The contact carrier is guided by movable slide plates disposed on either side thereof and movable along with the contact carrier as a contact assembly. The guide plates also provide pivot recesses for pivot bosses of the contact carrier. The contact carrier is constrained to linear motion up to the point of contact between the movable contact and the stationary contact by a cam trace in the housing. After contact between the movable contact and the stationary contact, the contact carrier reaches a pocket defined by the cam trace, ceases linear movement and upwardly pivots to provide a wiping action between the movable contact and the stationary contact. Immediately upon reversed, pivoting and linear motion of the contact carrier a shearing action is provided between the movable contact and the stationary contact. A plurality of such modular switches are utilized in a freight elevator interlock system for regulating the opening and closing of the various doors and carriage of the freight elevator.
